Homohabilis is a species of the tribe Hominini, during the Gelasian and early Calabrian stages of the Pleistocene period, which lived between roughly 2.8 and 1.5 million years ago.

A team led by scientists Louis and Mary Leakey uncovered the fossilized remains during the time frame of 1960-1963 at Olduvai Gorge in Tanzania; these fossils were speculated to be a new species, and called Homohabilis, because they suspected that it was this slightly larger-brained early human that made the thousands of stone tools also found at Olduvai Gorge.

In its appearance and morphology, H. habilis is the least similar to modern humans of all species in the genus Homo, and its classification as Homo has been the subject of controversial debate since its first proposal in the 1960s.
