Mananjary Airport (IATA: MNJ, ICAO: FMSM) is a small regional airport serving the town of Mananjary on the southeastern coast of Madagascar. It provides essential air connectivity for a region that is otherwise difficult to access due to limited road infrastructure. The airport is operated under the authority of the Malagasy civil aviation administration and handles primarily domestic flights connecting Mananjary to Antananarivo and other regional destinations. Given the challenging terrain and frequent cyclone risk in the area, air transport plays a vital role for local residents and relief operations. The facility is modest in scale, with basic infrastructure suited to small turboprop aircraft. It serves as an important lifeline for the Mananjary district, which is home to the Antambahoaka people and is known for its canal system and fishing industry.
