John Russell Napier, MRCS, LRCP, D.Sc. (1917 – 29 August 1987) was a British primatologist, paleoanthropologist, and physician, who is notable for his work with Homo habilis and OH 7, as well as on human and primate hands/feet. During his life he was widely considered a leading authority on primate taxonomy, but is perhaps most famous to the general public for his research on Bigfoot.
