The Hewitt's red rock hare is a species of mammal in the family Leporidae. It had previously been classified as a subspecies of Pronolagus rupestris, but is now regarded as its own species due to differences in morphology and genetic differences in cytochrome b, and 12S rRNA.

Leporidae is the family of rabbits and hares, containing over 70 species of extant mammals in all. The Latin word Leporidae means "those that resemble lepus" (hare). Together with the pikas, the Leporidae constitute the mammalian order Lagomorpha. Leporidae differ from pikas in that they have short, furry tails and elongated ears and hind legs.
