Faya is a the largest city in northern Chad, the capital of Bourkou-Ennedi-Tibesti prefecture. It has a population of 9,867 (as of 1993).

During the colonial era, the town was renamed Largeau, while on independence it was initially known as Faya-Largeau.

Due to the considerable underground water supply in the town, the main industry is agriculture, while three lakes lie immediately north of Faya.
