South Kurzeme is Latvia's largest municipality, covering an area of 3,591 square kilometres (1,386 sq mi).^[1] It is located in the southwestern part of the Courland region in western Latvia, on the coast of the Baltic Sea. It borders Ventspils Municipality to the north, Kuldīga Municipality to the northeast, and Saldus Municipality to the east. It surrounds the port city of Liepāja in the west.^[6] It also borders the Lithuanian counties of Klaipėda and Telšiai to the south and southeast respectively. The westernmost point of Latvia is located at Cape Bernāti in Nīca Parish south of Liepāja.^[7][8]

The coastline of South Kurzeme Municipality is over 100 kilometres (62 mi) long.^[9] Erosion of the coast north of Liepāja has been accelerated because breakwaters at Liepāja's seaport intercept sand drifting northward along the coast. The coast south of Liepāja features sandy beaches and dunes, behind which are lagoons and marshy plains. The largest of the lagoons are Lake Liepāja and Lake Tosmare [lv] on the municipality's border with Liepāja, and Lake Pape near the Lithuanian border.^[10] The Rietumkursa Upland [lv] rises east of the coastal lowlands, its highest point being Krievukalns [lv] at 190 metres (620 ft) in Embūte Parish.^[2]

Rivers in the municipality include the Bārta which flows from its headwaters in Lithuania into Lake Liepāja; and the Durbe [lv] and Tebra, which join to form the Saka [lv] at the village of the same name. The Saka drains into the Baltic Sea at Pāvilosta.

Pape Nature Reserve covers 10,853 hectares (26,820 acres) and protects Lake Pape and the surrounding land areas.^[11] It forms the terrestrial component of the Pape Wetland Complex Ramsar site, which also covers the adjacent marine area and has a total area of 51,725 hectares (127,820 acres).^[12][13] Bernāti Nature Park [lv] protects Cape Bernāti and Pūsēnu Hill, Latvia's highest sand dune at 37 metres (121 ft).^[8] Grīņu Nature Reserve is located in the northern part of the municipality.
