South African cheetah The South African cheetah ("Acinonyx jubatus jubatus"), also known as the Namibian cheetah, is the most numerous and the nominate cheetah subspecies native to Southern Africa.

In Namibia, cheetahs are mostly found in farmlands. The South African cheetah was first described by the German zoologist Johann Christian Daniel von Schreber under the trinomen "Felis jubatus jubatus" in the Dutch Cape Colony in 1775.
