Nouakchott–Oumtounsy International Airport (IATA: NKC, ICAO: GQNO) (Arabic: مطار نواكشوط الدولي - أم التونسي) is an international airport serving Nouakchott, the capital of Mauritania. It is located 25 kilometres north of the city. The airport opened in June 2016 as the replacement for Nouakchott International Airport.
Egis Group designed the airport, which is the largest project in Mauritania since 1960. The Government of Mauritania approved the plan on 13 October 2011, and local company Najah for Major Works (NMW) started construction the following month.
Oumtounsy Airport opened on 23 June 2016, in time for the 27th Arab League summit in late July.
