Gibraltar International Airport, previously known as North Front Airport, (IATA: GIB, ICAO: LXGB) is the civilian airport that serves the British overseas territory of Gibraltar. The runway and aerodrome is owned by the Ministry of Defence (MoD), and operated by the Royal Air Force (RAF) as RAF Gibraltar. Civilian operators use the civilian-operated terminal. National Air Traffic Services (NATS) hold the contract for provision of air navigation services at the airport.

In 2024, the civilian airport handled 424,386 passengers and 97,697 kilograms (215,385 pounds) of cargo on 3,628 total flights. Winston Churchill Avenue (the main road heading towards the land border with Spain) intersects the airport runway, and in the past had to be closed for aircraft movements. Since March 2023 there is a tunnel which allows traffic to flow whilst aircraft are landing or taking off. Pedestrians can still cross the runway when the road is open, which offers a shorter route than via the tunnel. The History Channel programme Most Extreme Airports ranked the airport the fifth most extreme airport in the world, ahead of the now-defunct Kai Tak Airport with its infamous right-hand turn approach over central Hong Kong before landing, but behind Princess Juliana International Airport, famous for its low-altitude approaches over a public beach. It is exposed to strong cross winds around the 'rock' and across the Bay of Gibraltar, making landings in winter particularly challenging.

Prior to its bankruptcy, Monarch Airlines was the largest operator at Gibraltar, but it entered administration and ceased operations in October 2017. As of 2021 easyJet is the largest airline operator, with the airport also being served by British Airways.

Although located in Gibraltar, the airport is also used by people travelling to or from neighbouring parts of southern Spain such as the Costa del Sol and the Campo de Gibraltar.
