Royal Air Force Castletown or more simply RAF Castletown, is a former Royal Air Force satellite station that operated during the Second World War. Built near to Castletown in Caithness, Scotland the station opened in 1940 and closed in 1945. Initially built to provide a base for fighter cover for the Royal Navy base at Scapa Flow, it later became an air-sea rescue base as well, before closing just after the end of the war in Europe.
