RAF Castle Combe was a Second World War Royal Air Force station situated half a mile southeast of Castle Combe in Wiltshire, England. The Castle Combe airfield opened in May 1941. The land which the airfield occupied belonged to the Castle Combe estate, which was owned by the Gorst family. It was used as a practice landing ground by nearby RAF Hullavington, home of No. 9 Service Flying Training School. Flying training expanded considerably and the facilities were upgraded. Waterlogging was a frequent problem for the grass surface, so two runways of Sommerfeld Tracking were laid and a tarmac perimeter track constructed around the field. There were five hangars on the eastern and south-eastern side of the site; the control tower is still extant.
