The korrigum (Damaliscus lunatus korrigum), also known as Senegal hartebeest, is a subspecies of the tsessebe, an African antelope. As of 2008, its total population was estimated at maximally 2650 animals. Korrigum formerly occurred from southern Mauritania and Senegal to western Chad, but has undergone a dramatic decline since the early 1900s because of displacement by cattle and uncontrolled hunting for meat. The species no longer occurs in Mauritania, Mali, Senegal and The Gambia, they probably no longer occur in northern Togo, Nigeria or western Chad, except as vagrants. Grubb, P. (2005).
