The Portuguese explorer Diogo Cão made two voyages along the west coast of Africa in the 1480s.

On his first voyage (1482-1483), he discovered the Congo River, and contacted the Bakongo kingdom further upstream. He followed the African coast southward until Cape St. Mary in Angola.

On his second voyage (1485-1486), he reached even further south, to Cape Cross in Namibia. He also sailed a short way up the Congo. It is not known whether he returned from this voyage.
