The waterbuck (Kobus ellipsiprymnus) is a large antelope found widely in Sub-Saharan Africa.

Waterbuck stand 120 to 136 centimetres (47 to 54 in) at the shoulder. Males weigh 200–300 kilograms (440–660 lb) and females 160–200 kilograms (350–440 lb). Their coats are reddish brown in colour and become progressively darker with age; they have a white 'bib' under their throats and white on their rumps. The waterproofing secretions of the waterbuck's sweat glands produces an unpleasant odor in its meat, unless the animal is skinned carefully. According to African myth the meat of the waterbuck is not edible, but this is untrue—whilst not especially tasty, waterbuck venison is safe to eat. The long spiral structured horns, found only in males, sweep back and up.

Waterbuck are found in scrub and savanna areas near water where they eat grass. Despite its name, the waterbuck does not spend much time in the water, but will take refuge there to escape predators. Waterbuck are diurnal. Females gather in herds of between two and six hundred individuals. Males keep territories of around three hundred acres (1.2 km²) during their prime. They usually lose their territories before the age of ten.
