Bir Moghrein Airport is a small regional airstrip serving the remote town of Bir Moghrein, located in the Tiris Zemmour region of far northern Mauritania near the border with Western Sahara and Morocco. The airport provides essential air access to a sparsely populated desert area where road travel can be extremely difficult and time-consuming. The facility is modest in scale, reflecting the limited population and economic activity of the surrounding region. It primarily supports government, military, and occasional charter operations rather than scheduled commercial airline service. The area is known historically as Fort Trinquet during the French colonial period.
