Kalajoki Airfield (ICAO: EFKO) is a small general aviation airport located near the town of Kalajoki on the western coast of Finland, in the North Ostrobothnia region. It serves private pilots, flight training, and light aircraft operations rather than scheduled commercial airline services. The airfield sits close to the Gulf of Bothnia and is in proximity to Kalajoki's well-known beach resort area, which draws tourists during summer months. Operations at the field are typical of Finland's numerous small regional airfields, supporting local aviation clubs and private flights.
