Antoine Simon Airport (IATA: CYA, ICAO: MTCA) is a commercial airport in Haiti. It is the fourth largest airport in Haiti for passenger traffic and is 9 kilometres (5.6 mi) north of Les Cayes, a Caribbean coastal city in Haiti's Southern peninsula.

The airport is named after François C. Antoine Simon, the 18th President of Haiti (1908–1911). It was financed and built by the Haitian government and inaugurated on 7 May 2005 by then Prime Minister Gérard Latortue. Taiwan financed the construction of the access road to the airport.

On February 1, 2013, Haiti laid the first stone on the expansion of the Antoine-Simon Airport. The Autorité Aéroportuaire Nationale plans to make it an international airport by extending the runway to 3,000 metres (9,800 ft) and adding a terminal with customs and other services. Both runway ends have displaced thresholds. The Cayes non-directional beacon (Ident: CAY) is located 0.4 nautical miles (0.7 km) southeast of the runway.

The project is part of broader efforts to ramp up infrastructure development in Haiti's South department. Haiti officials (Prime Minister Laurent Lamothe and Tourism Minister Stephanie Villedrouin) suggested that the airport would open up completely the southern region as the country sees tourism as a promising sector capable of creating thousands of jobs in the region.

Another airport is being built on the neighboring island of Île-à-Vache.
