Glacier Park International Airport (IATA: FCA, ICAO: KGPI, FAA LID: GPI) is in Flathead County, Montana, United States, six miles northeast of Kalispell. The airport is owned and operated by the Flathead Municipal Airport Authority, a public agency created by the county in 1974. The airport is near Glacier National Park.

The airport's ICAO code was KFCA, and most airlines still use that code for reservations purposes. Most U.S. airports use the same three-letter location identifier for the FAA and IATA, but Glacier Park International Airport is GPI to the FAA and FCA to the IATA (which assigned GPI to Guapi Airport in Colombia).
