Kelp forest off the coast of Western Cape, South Africa

Temperate Southern Africa is a biogeographic region of the Earth's seas, comprising the temperate waters of southern Africa, where the Atlantic Ocean and Indian Ocean meet. It includes the coast of South Africa and Namibia, and reaches into southern Angola. It also includes the remote islands of Amsterdam and Saint-Paul, to the east in the southern Indian Ocean.

Temperate Southern Africa is a marine realm, one of the great biogeographic divisions of the world's ocean basins.

The boundary between the Temperate Southern Africa and Western Indo-Pacific marine realms is near Lake St. Lucia, in South Africa near the border with Mozambique. The realm extends up the Atlantic coast of Africa to Tômbua in southern Angola, where it transitions to the Tropical Atlantic realm.


The Temperate Southern Africa realm is further subdivided into three marine provinces. Benguela province includes the Atlantic portion of the realm, influenced by the cold Benguela Current. Aghulhas province includes the rest of the South Africa's southern and eastern coasts which are influenced by the warm Agulhas Current. The Cape of Good Hope is the boundary between the Benguela and Agulhas provinces. Amsterdam and St. Paul islands are a separate province.

The Benguela and Agulhas marine provinces are divided into two marine ecoregions.
