Key West International Airport (IATA: EYW, ICAO: KEYW, FAA LID: EYW) is a county-owned public airport two miles (3 km) east of Key West, in Monroe County, Florida.

Key West International Airport covers 255 acres (103 ha) and has one asphalt runway (9/27) 4,801 x 100 ft (1,463 x 30 m). In 2006 the airport had 94,408 aircraft operations, average 258 per day: 51% general aviation, 29% air taxi, 14% military and 6% scheduled airline. 60 aircraft are based at EYW, 39 single engine and 21 multi-engine.

The Key West Airport has two terminals designed by Mark Mosko/Dwane Stark of URS; Mosko also did work on the Baltimore/Washington International Airport. The older one opened in 1957 and now serves arriving passengers. The newer terminal opened in February 2009 and serves departing passengers. With an area of about 30,000 square feet (2,800 m2), it more than doubled the terminal size. Parking for 300 vehicles is at ground level beneath the newer terminal—150 spaces for rental cars and 150 for the public.
