Laghouat (English: Laghwat French: Laghouat Arabic: الأغواط‎) is the capital of the Laghouat Province, Algeria, 400 km (250 mi) south of the Algerian capital Algiers. Located in the Amour Range of the Saharan Atlas, the town is an oasis on the north edge of the Sahara Desert. It is an important administrative and military center and marketplace, and is known for rug and tapestry weaving.

Laghouat traces its history to at least the 11th century. It was ruled by the Ottoman Turks in 1786 and annexed to Beylik of Titteri (Médéa). The town experienced the brutal Siege of Laghouat in 1852, and came under French colonial rule until 1962. Since 1974, it has been the seat of a province of the same name.

The population of the town was 126,291 inhabitants in 2005.[not verified in body] There are natural gas deposits in the region, and nearby Hassi R’Mel has the largest natural gas reserve in Africa. The city is served by Laghouat Airport
