Fairfax Airport was an airport in Kansas City, Kansas from 1921 until it closed in 1985. It is most famously associated with the construction of most of the B-25 Mitchell bombers.
The airport was directly across the Missouri River from Kansas City Downtown Airport and served as an air strip for plane manufacturers and repairs in the city's Fairfax district, as well as postal delivery. Passenger service in the area was handled by its Missouri sister (although Braniff briefly used it). Its IATA designation was KCK.
