Overberg is a district in South Africa to the east of Cape Town beyond the Hottentots-Holland mountains. It lies along the Cape Province's south coast between the Cape Peninsula and the region known as the Garden Route in the east. The boundaries of the Overberg are the Hottentots-Holland mountains in the West; the Riviersonderend Mountains, part of the Cape Fold Belt, in the North; the Atlantic and Indian Oceans in the South and the Breede River in the East.

The area has always been considered as the breadbasket of the Cape and is largely given to grain farming — mainly wheat. The wheat fields are a major breeding ground for South Africa's national bird, the Blue Crane. Another important food farmed in the Overberg is fruit with the Elgin Valley being the second largest supplier of fruit in South Africa.

Nestled in the Overberg, one can find the Kogelberg Biosphere Reserve (recognised and registered with UNESCO) populated with a large diversity of flowering plants not found anywhere else in the fynbos biome.
