Headcorn Aerodrome (ICAO: EGKH) is a private airfield in Kent, England. The airfield is located 8 NM (15 km; 9.2 mi) south of Maidstone; about 32 miles (51 km) southeast of London.

Opened in 1943 during the Second World War, it was named RAF Lashenden. It became a prototype for the temporary Advanced Landing Ground airfields that were built in France after D-Day, when the need for advanced landing fields became urgent as the Allied forces moved east across France and Germany. RAF Lashenden was used by the Royal Air Force, Royal Canadian Air Force and United States Army Air Forces before closing in September 1945.

After the war, the airfield reverted to farmland until the present private grass airfield was opened in the late 1960s.
