Nagasaki Airport (長崎空港, Nagasaki Kūkō) (IATA: NGS, ICAO: RJFU) is a second-class airport located off the coast of Ōmura, Nagasaki Prefecture, Japan. The airport was built over an existing island located in the center of Ōmura Bay, with some areas that were reclaimed.

Nagasaki Airport was built to replace the former airport called Omura Airport, which was located on the mainland and had a shorter runway of 1,200 metres (3,900 ft). The former airport was transferred to the Japan Self-Defense Force in 2011, and was renamed into Omura Air Base.

Oriental Air Bridge, a regional airline is based at the airport.
