The grey rhebok (Pelea capreolus), locally known as the vaalribbok in Afrikaans, is a species of antelope native to South Africa, Lesotho, and Eswatini. The specific name capreolus is Latin for ‘little goat’. The grey rhebok is a medium-sized antelope weighing 19–30 kilograms (42–66 lb) with a long neck and narrow ears. The coat is short and dense and coloured in various shades of grey. Only the males carry horns, which are straight, sharp, ringed at the base, and around 15–25 centimetres (5.9–9.8 in) long.
