The riverine rabbit, also known as the bushman rabbit or bushman hare, is a rabbit with an extremely limited distribution area, found only in the central and southern regions of the Karoo Desert of South Africa's Northern Cape Province. It is the only member of the genus Bunolagus because of unique traits that separate it from the other leporids. It is one of the most endangered mammals in the world, with only around 500 living adults, and 1500 overall.

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.
