town, south-central Morocco. It lies on the Saharan side of the High Atlas Mountains and is situated in the valley of the River Ouarzazate near its juncture with the River Drâa. The town originated as a military post during the French occupation (1932–56). Still a military centre with a fortress, it is also an important oasis and road junction linked to Marrakech by way of n'Tichka Pass.

Ouarzazate is situated in an arid region that extends from the crests of the High Atlas southward to the borders of the Sahara. Habitations exist only in the valleys, chiefly those of the Dadès and Drâa. The region's greatest economic resource lies in the manganese mines of Imini and the cobalt mines of Bou-Azzer, but it also has large deposits of copper. The agricultural potential of the Drâa valley was enhanced in the early 1970s with the completion in 1971 of Mansour ed-Dabhabi dam 10 miles (16 km) downstream from Ouarzazate. Pop. (2004) 56,616.
