The Barbary sheep (Ammotragus lervia), also known as aoudad (pronounced is a species of caprine native to rocky mountains in North Africa. Six subspecies have been described. Although it is rare in its native North Africa, it has been introduced to North America, southern Europe, and elsewhere. It is also known in the Berber language as waddan or arwi, and in former French territories as the moufflon. While this is the only species in genus Ammotragus, six subspecies have been described. Although it is rare in its native North Africa, it has been introduced to North America, southern Europe, and elsewhere.

Barbary sheep stand 75 to 110 cm (2.46 to 3.61 ft) tall at the shoulder, with a length around 1.5 m (4 ft 11 in), and weigh 30 to 145 kg (66 to 320 lb) . They are sandy-brown, darkening with age, with a slightly lighter underbelly and a darker line along the back. Upper parts and the outer parts of the legs are a uniform reddish- or grayish-brown. Some shaggy hair is on the throat (extending down to the chest in males) with a sparse mane. Their horns have a triangular cross-section. The horns curve outward, backward, then inward, and can exceed 76 cm (30 in) in length. The horns are fairly smooth, with slight wrinkles evident at the base as the animal matures.

Barbary sheep naturally occur in northern Africa in Morocco, Algeria, Tunisia, northern Chad, Egypt, Libya, northern Mali, Mauritania, Niger, and Sudan (west of the Nile, and in the Red Sea Hills east of the Nile).

Barbary sheep have been introduced to southeastern Spain, the southwestern United States[8] (Chinati Mountains on La Escalera Ranch, Guadalupe Mountains National Park, Palo Duro Canyon, the Trans-Pecos, and other parts of Texas and New Mexico), Niihau Island (Hawaii), Mexico, and some parts of Africa. They have become common in a limited region of southeastern Spain, since its introduction in 1970 to Sierra Espuña regional park as a game species. Its adaptability enabled it to colonise nearby areas quickly, and private game estates provided other centers of dispersion. The species is currently expanding, according to recent field surveys, now being found in the provinces of Alicante, Almería, Granada, and Murcia.[9] This species is a potential competitor to native ungulates inhabiting the Iberian Peninsula. The species has also been introduced to La Palma (Canary Islands), and has spread throughout the northern and central parts of the island, where it is a serious threat to endemic vegetation.[10] Aoudad has also been introduced in Croatia several times and there is a population in Mosor.

Barbary sheep are found in arid mountainous areas where they graze and browse grasses, bushes, and lichens. They are able to obtain all their metabolic water from food, but if liquid water is available, they drink and wallow in it. Barbary sheep are crepuscular - active in the early morning and late afternoon and rest in the heat of the day. They are very agile and can achieve a standing jump over 2 metres (7 ft). They are well adapted to their habitat, which consist of steep, rocky mountains and canyons. They often flee at the first sign of danger, typically running uphill. They are extremely nomadic and travel constantly via mountain ranges. Their main predators in North Africa were the Barbary leopard, the Barbary lion, and caracal, but now humans, feral dogs, competition due to overgrazing by domestic animals and drought threaten their populations.
