The Overberg District Municipality is located in the Western Cape Province and forms the southern-most area of Africa. The Overberg District Municipality is an amalgamation of the magisterial districts of Caledon, Hermanus, Bredasdorp and Swellendam. It is bordered by the municipal areas of the City of Cape Town, and the Boland and Eden District Municipalities.

The coastline of Overberg District Municipality varies dramatically, from white sandy beaches to rocky cliffs. The Atlantic and Indian oceans meet at Cape Agulhas, which is the southern-most tip of the African continent.

The Overberg District Municipality is endowed by rich natural and cultural resources and landscapes, the most prominent of which are associated with the coastal zone, the indigenous Fynbos vegetation on the coastal plateau and the dry Succulent Karoo environment of the Klein Karoo.

The main access route to the region are the national road (N2) via Sir Lowry's Pass and Houw Hoek Pass in the west, and Swellendam in the east. Cape Hangklip guards the coastal regional route (R44) in the west. Various mountain passes provide access from the north (including the R43, R45, R317 and R324).
