Gangneung Air Base (IATA: KAG, ICAO: RKNN) is an airbase holding the 18th fighter wing of the Republic of Korea Air Force.

In the past, this airfield also used to handle civilian air traffic.

The passenger handling functions of this airfield were closed prior to the opening of Yangyang International Airport.

In 1969, Korean Air Lines YS-11 flying from Gangneung Airbase to Gimpo International Airport in Seoul was hijacked by a North Korean agent and forced to land in the North; seven of the passengers and all four crew members among them did not return to South Korea.
