Kangerlussuaq Airport (Greenlandic: Mittarfik Kangerlussuaq, Danish: Søndre Strømfjord Lufthavn) (IATA: SFJ, ICAO: BGSF) is an airport in Kangerlussuaq, a settlement in the Qeqqata municipality in central-western Greenland. Alongside Narsarsuaq Airport, it is one of only two civilian airports in Greenland large enough to handle large airliners.

The Kangerlussuaq Airport is located away from the coast, and hence less prone to fog and wind in comparison with other airports in Greenland. Kangerlussuaq Airport is the international hub for Air Greenland. The Kangerlussuaq area has very few inhabitants, around 500, so few passengers have their origin or destination here. Most passengers change plane.

Kangerlussuaq Airport terminal is open for 24 hours during summer. Hotel Kangerlussuaq, with a 70-room capacity and a restaurant, is located within the terminal building of the airport, providing accommodation for transferring passengers. Other amenities include a night-club and a self-service bar during daytime. Several tourism outfitters share an office in the terminal, alongside the Tourist Office.
