The royal antelope ("Neotragus pygmaeus") is a West African antelope, recognised as the world's smallest antelope. It was first described by Swedish zoologist Carl Linnaeus in 1758. It stands up to merely at the shoulder and weighs . A characteristic feature is the long and slender legs, with the hindlegs twice as long as the forelegs. Horns are possessed only by males; the short, smooth, spiky horns measure and bend backward. The soft coat is reddish to golden brown, in sharp contrast with the white ventral parts. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles.
