New Guinea (Tok Pisin: Niugini; Hiri Motu: Niu Gini; Indonesian: Papua, or Nugini,[a] historically Irian) is the world's second-largest island with an area of 785,753 km2 (303,381 sq mi). Located in Oceania in the southwestern Pacific Ocean, the island is separated from Australia by the 150-kilometre (81-nautical-mile; 93-mile) wide Torres Strait, though both landmasses lie on the same continental shelf. Numerous smaller islands are located to the west and east. The eastern half of the island is the major land mass of the independent state of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Papua, Central Papua, Highland Papua, South Papua, and West Papua. The largest cities on the island are Jayapura (capital of Papua, Indonesia) and Port Moresby (capital of Papua New Guinea).

The island has been known by various names:
The name Papua was used to refer to parts of the island before contact with the West. Its etymology is unclear; one theory states that it derived from Tidore, the language used by the Sultanate of Tidore. Expedition by Sultan of Tidore, with Sahmardan, Sangaji of Patani and Gurabesi managed to conquer some areas in New Guinea which was then reorganised to Korano Ngaruha (lit. Four Kings) or Raja Ampat, Papo Ua Gamsio (lit. The Papua Nine Negeri), and Mafor Soa Raha (lit. The Mafor Four Soa). The name comes from the words papo (to unite) and ua (negation), which means "not united" or, "territory that geographically is far away (and thus not fully integrated to Tidore proper)".
Anton Ploeg reports that the word papua is often said to be derived from the Malay word papua or pua-pua, meaning "frizzly-haired", referring to the very curly hair of the inhabitants of these areas. Another possibility, put forward by Sollewijn Gelpke in 1993, is that it comes from the Biak phrase sup i papwa, which means 'the land below [the sunset]', and refers to the islands west of the Bird's Head, as far as Halmahera. The name Papua came to be associated with this area, and more especially with Halmahera, which was known to the Portuguese by this name during the era of their colonization in this part of the world.
When Portuguese and Spanish explorers arrived in the island via the Spice Islands, they also referred to the island as Papua. However, Westerners, beginning with Spanish explorer Yñigo Ortiz de Retez in 1545, used the name New Guinea, referring to the similarities of the features of the indigenous peoples to those of native Africans of the Guinea region of the continent. The name is one of several toponyms sharing similar etymologies, ultimately meaning "land of the blacks" or similar meanings, in reference to the dark skin of the inhabitants.
The Dutch, who arrived later under Jacob Le Maire and Willem Schouten, called it Schouten island. They later used this name only to refer to islands off the north coast of Papua proper, the Schouten Islands or Biak Island. When the Dutch colonized this island as part of the Dutch East Indies, they called it Nieuw Guinea.
The name Irian was used in the Indonesian language to refer to the island and Indonesian province, as Irian Barat (West Irian) Province and later Irian Jaya Province. The name Irian was suggested during a tribal committee meeting in Tobati, Jayapura, formed by Atmoprasojo under van Eechoed, to decide of new name because of negative association of Papua. Frans Kaisiepo, the committee leader suggested the name from Mansren Koreri myths, Iri-an from the Biak language of Biak Island, meaning "hot land" referring to the local hot climate, but also from Iryan which means heated process as a metaphor for a land that is entering a new era. In Serui Iri-an (lit. land-nation) means "pillar of nation", while in Merauke Iri-an (lit. placed higher-nation) means "rising spirit" or "to rise". The name was promoted in 1945 by Marcus Kaisiepo, brother of Frans Kaisiepo. The name was politicized later by Marthin Indey, Silas Papare, and others with the Indonesian acronym 'Ikut Republik Indonesia Anti Nederland' (Join the Republic of Indonesia oppose the Netherlands). The name was used until 2001, when Papua was again used for the island and the province. The name Irian, which was originally favored by natives, is now considered to be a name imposed by the authority of Jakarta.
New Guinea is an island to the north of the Australian mainland, south of the equator. It is isolated by the Arafura Sea to the west, and the Torres Strait and Coral Sea to the east. Sometimes considered to be the easternmost island of the Indonesian archipelago, it lies north of Australia's Top End, the Gulf of Carpentaria and Cape York Peninsula, and west of the Bismarck Archipelago and the Solomon Islands archipelago.
Politically, the western half of the island comprises five provinces of Indonesia: Papua, Central Papua, Highland Papua, South Papua, and West Papua. The eastern half forms the mainland of the country of Papua New Guinea.
The shape of New Guinea is often compared to that of a bird-of-paradise (indigenous to the island), and this results in the usual names for the two extremes of the island: the Bird's Head Peninsula in the northwest (Vogelkop in Dutch, Kepala Burung in Indonesian; also known as the Doberai Peninsula), and the Bird's Tail Peninsula in the southeast (also known as the Papuan Peninsula).
A spine of east–west mountains, the New Guinea Highlands, dominates the geography of New Guinea, stretching over 1,600 km (1,000 mi) across the island, with many mountains over 4,000 m (13,100 ft). The western half of the island contains the highest mountains in Oceania, with its highest point, Puncak Jaya, reaching an elevation of 4,884 m (16,023 ft). The tree line is around 4,000 m (13,100 ft) elevation, and the tallest peaks contain equatorial glaciers—which have been retreating since at least 1936. Various other smaller mountain ranges occur both north and west of the central ranges. Except in high elevations, most areas possess a warm humid climate throughout the year, with some seasonal variation associated with the northeast monsoon season.
Another major habitat feature is the vast southern and northern lowlands. Stretching for hundreds of kilometres, these include lowland rainforests, extensive wetlands, savanna grasslands, and some of the largest expanses of mangrove forest in the world. The southern lowlands are the site of Lorentz National Park, a UNESCO World Heritage Site. The northern lowlands are drained principally by the Mamberamo River and its tributaries on the western side, and by the Sepik on the eastern side. The more extensive southern lowlands are drained by a larger number of rivers, principally the Digul in the west and the Fly in the east. The largest island offshore, Dolak, lies near the Digul estuary, separated by a strait so narrow it has been named a "creek".
New Guinea contains many of the world's ecosystem types: glacial, alpine tundra, savanna, montane and lowland rainforest, mangroves, wetlands, lake and river ecosystems, seagrasses, and some of the richest coral reefs on the planet.
The entire length of the New Guinea Highlands system passes through New Guinea as a vast watershed. The northern rivers flow into the Pacific Ocean, the southern rivers into the Arafura Sea and the Gulf of Papua. On the north side, the largest rivers are the Mamberamo, Sepik and Ramu. Mamberamo was born from the confluence of two large inland rivers. Tariku comes from the west to the east and Taritatu from the east. These rivers meander through swamps with huge internal descents and then merge. The Mamberamo thus formed reaches the ocean by breaking through the Coastal Mountains. Mamberamo River is navigable to Marine Falls. The Sepik is a much more important river. Similarly, it collects water from a spacious pool. It is 1,100 kilometers from the Victor Emanuel Range to the estuary, making it the longest river in New Guinea. The winding, muddy, sluggish river can be navigated for 500 km. Ramu is a 650 km long river. Its lower section is navigable, but its upper flow is high-falling, fast-flowing. The energy of the river is used by a power plant near the city of Kainantu. On the south side, the most significant rivers are Pulau, Digul, Fly, Kikori and Purari. The largest river in the western part of the island is Digul. It originates from the Star Mountains, which rise to an altitude of 4,700 m. The coastal plain is bordered by a swamp world hundreds of kilometers wide. Digul is the main transport route to the fertile hills and mountains within the island. The river Fly is born near the eastern branches of the Digul. It is named after one of the ships of the English Royal Fleet, which first sailed into the mouth of the river in 1845. The total length of the river is 1,050 km. Smaller boats can sail 900 km on the river. The estuary section, which decomposes into islands, is 70 km wide. The tide of the sea can have an effect of up to 300 kilometers. Strickland, a tributary of the Fly, reaches the Papuan Plain through wild gorges. Fly and Strickland together form the largest river in New Guinea. The many rivers flowing into the Gulf of Papua form a single delta complex. The rivers of the island are extremely rich in water due to the annual rainfall of 2,000–10,000 mm. According to a modest calculation, the New Guinea River carries about 1,500 km3/a (48,000 m3/s) of water into the sea. Fly alone carries more water 238 km3/a (7,500 m3/s) than all the rivers in Australia combined.
The island of New Guinea lies to the east of the Malay Archipelago, with which it is sometimes included as part of a greater Indo-Australian Archipelago. Geologically it is a part of the same tectonic plate as Australia. When world sea levels were low, the two shared shorelines (which now lie 100 to 140 metres below sea level), and combined with lands now inundated into the tectonic continent of Sahul, also known as Greater Australia. The two landmasses became separated when the area now known as the Torres Strait flooded after the end of the last glacial period.
New Guinea is differentiated from its drier, flatter, and less fertile southern counterpart, Australia, by its much higher rainfall and its active volcanic geology. Yet the two land masses share a similar animal fauna, with marsupials, including wallabies and possums, and the egg-laying monotreme, the echidna. Other than bats and some two dozen indigenous rodent genera, there are no pre-human indigenous placental mammals. Pigs, several additional species of rats, and the ancestor of the New Guinea singing dog were introduced with human colonization.
Prior to the 1970s, archaeologists called the single Pleistocene landmass by the name Australasia, although this word is most often used for a wider region that includes lands, such as New Zealand, which are not on the same continental shelf. In the early 1970s, they introduced the term Greater Australia for the Pleistocene continent. Then, at a 1975 conference and consequent publication, they extended the name Sahul from its previous use for just the Sahul Shelf to cover the continent.
The island of New Guinea is divided politically into roughly equal halves across a north–south line:
The current population of the island of New Guinea is about eleven million. Many believe human habitation on the island dates to as early as 50,000 BC, and first settlement possibly dating back to 60,000 years ago has been proposed. The island is presently populated by almost a thousand different tribal groups and a near-equivalent number of separate languages, which makes New Guinea the most linguistically diverse area in the world. Ethnologue's 14th edition lists 826 languages of Papua New Guinea and 257 languages of Western New Guinea, total 1073 languages, with 12 languages overlapping.[clarification needed] They can be divided into two groups, the Austronesian languages, and all the others, called Papuan languages for convenience. The term Papuan languages refers to an areal grouping, rather than a linguistic one, since so-called Papuan languages comprise hundreds of different languages, most of which are not related.
The separation is not merely linguistic; warfare among societies was a factor in the evolution of the men's house: separate housing of groups of adult men, from the single-family houses of the women and children, for mutual protection from other tribal groups. Pig-based trade between the groups and pig-based feasts are a common theme with the other peoples of southeast Asia and Oceania. Most societies practice agriculture, supplemented by hunting and gathering.
Current evidence indicates that the Papuans (who constitute the majority of the island's peoples) are descended from the earliest human inhabitants of New Guinea. These original inhabitants first arrived in New Guinea at a time (either side of the Last Glacial Maximum, approx 21,000 years ago) when the island was connected to the Australian continent via a land bridge, forming the landmass of Sahul. These peoples had made the (shortened) sea-crossing from the islands of Wallacea and Sundaland (the present Malay Archipelago) by at least 40,000 years ago.
The ancestral Austronesian peoples are believed to have arrived considerably later, approximately 3,500 years ago, as part of a gradual seafaring migration from Southeast Asia, possibly originating in Taiwan. Austronesian-speaking peoples colonized many of the offshore islands to the north and east of New Guinea, such as New Ireland and New Britain, with settlements also on the coastal fringes of the main island in places. Human habitation of New Guinea over tens of thousands of years has led to a great deal of diversity, which was further increased by the later arrival of the Austronesians and the more recent history of European and Asian settlement through events like transmigration.
With some 786,000 km2 of tropical land—less than one-half of one percent (0.5%) of the Earth's surface—New Guinea has an immense biodiversity, containing between 5 and 10 percent of the total species on the planet. This percentage is about the same amount as that found in the United States or Australia. A high percentage of New Guinea's species are endemic, and thousands are still unknown to science: probably well over 200,000 species of insect, between 11,000 and 20,000 plant species, and over 650 resident bird species. Most of these species are shared, at least in their origin, with the continent of Australia, which was until fairly recent geological times part of the same landmass (see Australia-New Guinea for an overview). The island is so large that it is considered 'nearly a continent' in terms of its biological distinctiveness.
In the period from 1998 to 2008, conservationists identified 1,060 new species in New Guinea, including 218 plants, 43 reptiles, 12 mammals, 580 invertebrates, 134 amphibians, 2 birds and 71 fish. Between 2011 and 2017, researchers described 465 previously undocumented plant species in New Guinea. As of 2019, the Indonesian portion of New Guinea and the Maluku Islands is estimated to have 9,518 species of vascular plants, of which 4,380 are endemic. In 2020, an international study conducted by a team of 99 experts cataloged 13,634 species representing 1,742 genera and 264 families of vascular plants for New Guinea and its associated islands (Aru Islands, Bismarck Archipelago, D'Entrecasteaux Islands, Louisiade Archipelago), making it the world's most floristically diverse island, surpassing Madagascar (11,488), Borneo (11,165), Java (4,598), and the Philippines (9,432).
Biogeographically, New Guinea is part of Australasia rather than the Indomalayan realm, although New Guinea's flora has many more affinities with Asia than its fauna, which is overwhelmingly Australian. Botanically, New Guinea is considered part of Malesia, a floristic region that extends from the Malay Peninsula across Indonesia to New Guinea and the East Melanesian Islands. The flora of New Guinea is a mixture of many tropical rainforest species with origins in Asia, together with typically Australasian flora. Typical Southern Hemisphere flora include the conifers Podocarpus and the rainforest emergents Araucaria and Agathis, as well as tree ferns and several species of Eucalyptus.
New Guinea has 284 species and six orders of mammals: monotremes, three orders of marsupials, rodents and bats; 195 of the mammal species (69%) are endemic. New Guinea has 578 species of breeding birds, of which 324 species are endemic. The island's frogs are one of the most poorly known vertebrate groups, totalling 282 species, but this number is expected to double or even triple when all species have been documented. New Guinea has a rich diversity of coral life and 1,200 species of fish have been found. Also about 600 species of reef-building coral—the latter equal to 75 percent of the world's known total. The entire coral area covers 18 million hectares off a peninsula in northwest New Guinea.
As of 2020, the Western portion of New Guinea, Papua and West Papua, accounts for 54% of the island's primary forest and about 51% of the island's total tree cover, according to satellite data.
The first inhabitants Indigenous people of New Guinea, from whom the Papuan people are probably descended, adapted to the range of ecologies and, in time, developed one of the earliest known agricultures. Remains of this agricultural system, in the form of ancient irrigation systems in the highlands of Papua New Guinea, are being studied by archaeologists. Research indicates that the highlands were an early and independent center of agriculture, with evidence of irrigation going back at least 10,000 years. Sugarcane was cultivated for the first time in New Guinea around 6000 BC.
The gardens of the New Guinea Highlands are ancient, intensive permacultures, adapted to high population densities, very high rainfalls (as high as 10,000 mm per year (400 in/yr)), earthquakes, hilly land, and occasional frost. Complex mulches, crop rotations and tillages are used in rotation on terraces with complex irrigation systems. Western agronomists still do not understand all of the practices, and it has been noted that native gardeners are as, or even more, successful than most scientific farmers in raising certain crops. There is evidence that New Guinea gardeners invented crop rotation well before western Europeans. A unique feature of New Guinea permaculture is the silviculture of Casuarina oligodon, a tall, sturdy native ironwood tree, suited to use for timber and fuel, with root nodules that fix nitrogen. Pollen studies show that it was adopted during an ancient period of extreme deforestation.
In more recent millennia, another wave of people arrived on the shores of New Guinea. These were the Austronesian people, who had spread down from Taiwan, through the South-east Asian archipelago, colonising many of the islands on the way. The Austronesian people had technology and skills extremely well adapted to ocean voyaging and Austronesian language speaking people are present along much of the coastal areas and islands of New Guinea. They also introduced pigs and dogs. These Austronesian migrants are considered the ancestors of most people in insular Southeast Asia, from Sumatra and Java to Borneo and Sulawesi, as well as coastal new Guinea.
The western part of the island was in contact with kingdoms in other parts of modern-day Indonesia. The Negarakertagama mentioned the region of Wanin and Sran, in eastern Nusantara as part of Majapahit's tributary. This 'Wanin' has been identified with the Onin Peninsula, part of the Bomberai Peninsula near the city of Fakfak., while 'Sran' had been identified as region of Kowiai, just south of Onin peninsula. The sultans of Tidore, in the Maluku Islands, claimed sovereignty over various coastal parts of the island. During Tidore's rule, the main exports of the island during this period were resins, spices, slaves and the highly priced feathers of the bird-of-paradise. In a period of constant conflict called 'hongi wars', in which rival villages or kingdoms would invoke the name of Tidore Sultan, rightly, for punitive expeditions for not fulfilling their tributary obligations, or opportunitively for competitions over resources and prestige. Sultan Nuku, one of the most famous Tidore sultans who rebelled against Dutch colonization, called himself "Sultan of Tidore and Papua", during his revolt in 1780s. He commanded loyalty from both Moluccan and Papuan chiefs, especially those of Raja Ampat Islands, from his base in Gebe. Following Tidore's subjugation as Dutch tributary, much of the territory it claimed in western part of New Guinea came under Dutch rule as part of Dutch East Indies.
The first European contact with New Guinea was by Portuguese and Spanish sailors in the 16th century. In 1526–27, Portuguese explorer Jorge de Meneses saw the western tip of New Guinea and named it ilhas dos Papuas. In 1528, the Spanish navigator Álvaro de Saavedra also recorded its sighting when trying to return from Tidore to New Spain. In 1545, Spaniard Íñigo Ortíz de Retes sailed along the north coast of New Guinea as far as the Mamberamo River, near which he landed on 20 June, naming the island 'Nueva Guinea'. The first map showing the whole island (as an island) was published in 1600 and shows it as 'Nova Guinea'. In 1606, Luís Vaz de Torres explored the southern coast of New Guinea from Milne Bay to the Gulf of Papua including Orangerie Bay, which he named Bahía de San Lorenzo. His expedition also discovered Basilaki Island naming it Tierra de San Buenaventura, which he claimed for Spain in July 1606. On 18 October, his expedition reached the western part of the island in present-day Indonesia, and also claimed the territory for the King of Spain.
A successive European claim occurred in 1828, when the Netherlands formally claimed the western half of the island as Netherlands New Guinea. Dutch colonial authority built Fort Du Bus an administrative and trading post established near Lobo, Triton Bay, but by 1835 had been abandoned. Considering that New Guinea had little economic value for them, the Dutch promoted Tidore as suzerain of Papua. By 1849, Tidore's borders had been extended to the proximity of the current international border between Indonesia and Papua New Guinea, as it formed extensive trade pact and custom of Uli-Siwa ( federation of nine ).
In 1883, following a short-lived French annexation of New Ireland, the British colony of Queensland annexed south-eastern New Guinea. However, the Queensland government's superiors in the United Kingdom revoked the claim, and (formally) assumed direct responsibility in 1884, when Germany claimed north-eastern New Guinea as the protectorate of German New Guinea (also called Kaiser-Wilhelmsland).
The first Dutch government posts were established in 1898 and in 1902: Manokwari on the north coast, Fak-Fak in the west and Merauke in the south at the border with British New Guinea. The German, Dutch and British colonial administrators each attempted to suppress the still-widespread practices of inter-village warfare and headhunting within their respective territories.
In 1905, the British government transferred some administrative responsibility over southeast New Guinea to Australia (which renamed the area "Territory of Papua"); and, in 1906, transferred all remaining responsibility to Australia. During World War I, Australian forces seized German New Guinea, which in 1920 became the Territory of New Guinea, to be administered by Australia under a League of Nations mandate. The territories under Australian administration became collectively known as The Territories of Papua and New Guinea (until February 1942).
Before about 1930, European maps showed the highlands as uninhabited forests. When first flown over by aircraft, numerous settlements with agricultural terraces and stockades were observed. The most startling discovery took place on 4 August 1938, when Richard Archbold discovered the Grand Valley of the Baliem River, which had 50,000 yet-undiscovered Stone Age farmers living in orderly villages. The people, known as the Dani, were the last society of its size to make first contact with the rest of the world. A 1930 expedition led by the prospector Michael Lehay also encountered an indigenous group in the highlands. The inhabitants, believing themselves to be the only people in the world and, having never seen Europeans before, initially believed the explorers to be spirits of the dead due to the local belief that a person's skin turned white when they died and crossed into the land of the dead.
Netherlands New Guinea and the Australian territories were invaded in 1942 by the Japanese. The Australian territories were put under military administration and were known simply as New Guinea. The highlands, northern and eastern parts of the island became key battlefields in the South West Pacific Theatre of World War II. Papuans often gave vital assistance to the Allies, fighting alongside Australian troops, and carrying equipment and injured men across New Guinea. Approximately 216,000 Japanese, Australian and U.S. soldiers, sailors and airmen died during the New Guinea Campaign.
Following the return to civil administration after World War II, the Australian section was known as the Territory of Papua-New Guinea from 1945 to 1949 and then as Territory of Papua and New Guinea. Although the rest of the Dutch East Indies achieved independence as Indonesia on 27 December 1949, the Netherlands regained control of western New Guinea.
During the 1950s, the Dutch government began to prepare Netherlands New Guinea for full independence and allowed elections in 1959; the elected New Guinea Council took office on 5 April 1961. The Council decided on the name of West Papua (Papua Barat) for the territory, along with an emblem, flag, and anthem to complement those of the Netherlands. On 1 October 1962, after some military interventions and negotiations, the Dutch handed over the territory to the United Nations Temporary Executive Authority, until 1 May 1963, when Indonesia took control. The territory was renamed West Irian (Irian Barat) and then Irian Jaya. In 1969, Indonesia, under the 1962 New York Agreement, organised a referendum named the Act of Free Choice, in which the military hand picked Papuan tribal elders to vote for integration with Indonesia.
There has been significant reported resistance to Indonesian integration and occupation, both through civil disobedience (such as publicly raising the Morning Star flag) and via the formation of the Organisasi Papua Merdeka (OPM, or Free Papua Movement) in 1965. Amnesty International has estimated more than 100,000 Papuans, one-sixth of the population, have died as a result of government-sponsored violence against West Papuans. Reports published by TRT World and De Gruyter Oldenbourg have put the number of killed Papuans since the start of the conflict at roughly 500,000.
From 1971, the name Papua New Guinea was used for the Australian territory. On 16 September 1975, Australia granted full independence to Papua New Guinea. In 2000, Irian Jaya was formally renamed "The Province of Papua" and a Law on Special Autonomy was passed in 2001. The Law established a Papuan People's Assembly (MRP) with representatives of the different indigenous cultures of Papua. The MRP was empowered to protect the rights of Papuans, raise the status of women in Papua, and to ease religious tensions in Papua; block grants were given for the implementation of the Law as much as $266 million in 2004. The Indonesian courts' enforcement of the Law on Special Autonomy blocked further creation of subdivisions of Papua: although President Megawati Sukarnoputri was able to create a separate West Papua province in 2003 as a fait accompli, plans for a third province on western New Guinea were blocked by the courts. Critics argue that the Indonesian government has been reluctant to establish or issue various government implementing regulations so that the legal provisions of special autonomy could be put into practice, and as a result special autonomy in Papua has "failed".
