Royal Air Force Kirkistown or more simply RAF Kirkistown is a former Royal Air Force satellite airfield located of Ballyhalbert, County Down, Northern Ireland.
It was a satellite to the RAF Fighter Command airfield at Ballyhalbert on the Ards Peninsula.
RAF Ballyhalbert opened officially on 28 June 1941 and the Kirkistown satellite airfield opened in July 1941. On 22 January 1942, No. 504 Squadron RAF moved to Kirkistown. In 1945, Ballyhalbert Airfield was designated a Royal Naval Air Station as "H.M.S. Corncrake", and Kirkistown Airfield was known as "H.M.S.
