The Middle Atlantic states, commonly shortened to Mid-Atlantic states, is a region of the United States generally located in the overlap between the Northeastern and Southeastern States. Its exact definition differs upon source, but the region usually includes New York, New Jersey, Pennsylvania, Delaware, Maryland, Washington, D. C., Virginia, and West Virginia. When discussing climate, Connecticut is sometimes included in the region, since its climate is closer to that of the Middle Atlantic states than the rest of the New England states. The Mid-Atlantic has played an important role in the development of American culture, commerce, trade, and industry; in the late 19th century, the Mid-Atlantic was called "the typically American" region by Frederick Jackson Turner.
European Americans of the mid-Atlantic region have ancestry from its settlement by the Dutch, Swedes, English Catholics, and Quakers through to the period of British rule and beyond to the current day. Religious pluralism existed, particularly in Maryland, which was the only colony in the original Thirteen Colonies to have a substantial Catholic minority population. After the American Revolution, the Mid-Atlantic region hosted each of the historic capitals of the United States, including the current federal capital, Washington, D. C. In the early part of the 19th century, New York and Pennsylvania overtook Virginia as the most populous states and the New England states as the country's most important trading and industrial centers. Large numbers of German, Irish, Italian, Jewish, Polish, and other immigrants transformed the region, especially coastal cities such as New York City, Newark, Philadelphia, and Baltimore, but also interior cities such as Pittsburgh, Rochester, Albany, and Buffalo. New York, with its skyscrapers, subways, and the Headquarters of the United Nations, emerged in the 20th century as an icon of modernity and American economic and cultural power. By the 21st century, the coastal areas of the Mid-Atlantic were thoroughly urbanized.
The Northeast Corridor and Interstate 95 link an almost contiguous sprawl of suburbs and large and small cities, forming the Mid-Atlantic portion of the Northeast megalopolis, one of the world's most important concentrations of finance, media, communications, education, medicine, and technology. The Mid-Atlantic is a relatively affluent region of the nation, having 43 of the 100 highest-income counties in the nation, based on median household income, and 33 of the top 100, based on per capita income. Most of the Mid-Atlantic states rank among the 15 highest-income states in the nation, by median household income and per capita income. The region is home to some of the most prestigious universities in the nation and the world, including Columbia University, Cornell University, Johns Hopkins University, the University of Pennsylvania, and Princeton University, which rank among the top 20 universities in the United States, and the top 25 universities in the world.
There are differing interpretations as to the composition of the Mid-Atlantic, with sources including in the region a number of states from New York to South Carolina. A United States Geological Survey publication describes the Mid-Atlantic Region as all of Maryland, Delaware, the District of Columbia, Pennsylvania, and Virginia, along with the parts of New Jersey, New York, and North Carolina that drain into the Delaware and Chesapeake Bays and the Albemarle and Pamlico Sounds. Sometimes, the region's nucleus is considered to be the area centered on the Washington metropolitan area, including Maryland, Delaware, Virginia, and West Virginia. In contrast to other definitions (where the Mid-Atlantic overlaps the Northeast and Southeast), the United States Census Bureau defines the Middle Atlantic as a subregion of the Northeast consisting exclusively of New York, New Jersey, and Pennsylvania.
West Virginia and Virginia are atypical of this region in a few ways. They are the only states to lie primarily within the Southern American dialect region, and the major religious tradition in both states is Evangelical Christian, 30% in Virginia and 39% in West Virginia. Although a few of West Virginia's eastern panhandle counties are considered part of the Washington, D.C. MSA, the major portion of the state is rural and there are no major or even large cities.

Shipping and trade have been important to the Mid-Atlantic economy since the beginning of the colonial era. The explorer Giovanni da Verrazzano was the first European to see the region in 1524. Henry Hudson later extensively explored that region in 1611 and claimed it for the Dutch, who then created a fur-trading post in Albany in 1614. Jamestown, Virginia was the first permanent English colony in North America, it was established seven years earlier in 1607.
From early colonial times, the Mid-Atlantic region was settled by a wider range of European people than in New England or the South. The Dutch New Netherland settlement along the Hudson River in New York and New Jersey, and for a time, New Sweden along the Delaware River in Delaware, divided the two great bulwarks of English settlement from each other. The original English settlements in the region notably provided refuge to religious minorities, Maryland to Roman Catholics and Pennsylvania to Quakers and Anabaptist Pennsylvania Dutch. In time, all these settlements fell under English colonial control, but the region continued to be a magnet for people of diverse nationalities.
The area that came to be known as the Middle Colonies served as a strategic bridge between the North and South. The New York and New Jersey campaign during the American Revolutionary War saw more battles than any other theater of the conflict. Philadelphia, midway between the northern and southern colonies, was home to the Continental Congress, the convention of delegates who organized the American Revolution. The same city was the birthplace of the Declaration of Independence in 1776 and the United States Constitution in 1787, while the United States Bill of Rights was drafted and ratified and the first Supreme Court of the United States sat for the first time, in the first capital under the Constitution at New York.
While early settlers were mostly farmers, traders, and fishermen, the Mid-Atlantic states provided the young United States with heavy industry and served as the "melting pot" of new immigrants from Europe. Cities grew along major ports, shipping routes, and waterways. Such flourishing cities included New York City and Newark on opposite sides of the Hudson River, Philadelphia on the Delaware River and Baltimore on the Chesapeake Bay.
