Rusingoryx is a genus of extinct alcelaphine bovid artiodactyl closely related to the wildebeest. It contains only one species, R. atopocranion, that lived on the plains of Kenya during the Pleistocene.[1] It was originally named as a species of Megalotragus.

Rusingoryx is known for its strange pointed nose with a large nasal dome. This structure represents an instance of convergent evolution with the crests of hadrosaurid dinosaurs, which were used for display and vocalization.[1][2][3] Studies have shown that the Rusingoryx is a specialized grazing animal, with a preference for arid grasslands.[4][2]

The first specimens, which were poorly preserved, were described in 1983, having been taken from a site called Bovid Hill on Rusinga Island in Lake Victoria.[3][5] Butchered bones found in 2011 with stone tools suggested that they had been killed by humans.[4][2] In 2016, remains of an additional 26 better preserved individuals were discovered.
