Cooper's Cave is a series of fossil-bearing breccia filled cavities located almost exactly between the well known South African hominid-bearing sites of Sterkfontein and Kromdraai and about 40 km Northwest of the City of Johannesburg, South Africa.

Cooper's has been investigated for fossils since 1938 when Julius Staz found a hominid (ape-man) tooth in the mine dumps at the site while leading a student visit to nearby Sterkfontei.nC.K "Bob" Brain worked at the site in 1954 and recovered a large number of fossil animals but reported no hominids. He also named the deposits Cooper's A and B. Surprisingly, more than forty years later, work by researchers and students on this collection of Brain's noted two hominid specimens - an isolated tooth and a crushed face. In 2001 Lee Berger discovered a new deposit near where Brain had worked and called it Cooper's D. With Duke University students, local technicians and South African students within days of opening these excavations, hominid remains were found. Cooper's D is now recognized at the fifth richest hominid site in the Cradle of Humankind World Heritage Site (behind Sterkfontein, Swartkrans, Drimolen and Kromdraai and one of the richest sites for early homninid stone tools of the Developed Olduwan culture, Excavations are still underway at Cooper's and are currently being directed by Christine Steininger and Lee Berger of the Institute for Human Evolution and the Bernard Price Institute for Palaeontological Research at the University of the Witwatersrand.
