Royal Air Force Croft or RAF Croft is a former Royal Air Force station located 4.6 miles (7.4 km) south of Darlington, County Durham, England and 8 miles (13 km) north east of Richmond, North Yorkshire. The site is also known locally as Croft Aerodrome or Neasham.
The first squadron to join the airfield was No. 78 Squadron RAF which arrived on 20 October 1941 flying both the Armstrong Whitworth Whitley Mk.V and the Handley Page Halifax Mk. II before leaving on 10 June 1942 when no units were stationed during the summer but on 1 October 1942 No. 419 Squadron RCAF has arrived with their Mk. III Vickers Wellingtons before re-equipping with the Halifax II and leaving on 10 November 1942. During this time on 7 November 1942 427 Squadron RCAF was formed at the airfield with a mixture of Mk III's and Mk X's Wellington before leaving on 4 May 1943.
The airfield also hosted No 1664 (Royal Canadian Air Force) Heavy Conversion Unit RAF starting from 10 May 1943 which trained new pilots to fly the new heavy bombers using the Mk II and the Mk IV Halifax before leaving on 7 December 1943. When three days later on the tenth 431 Squadron RCAF began using the airfield with the Halifax Mks V and III and the Avro Lancaster Mk.X before leaving on 7 June 1945 going to Canada. This squadron was joined by 434 Squadron RCAF which had joined on 11 December 1944 also flying the Halifax and the Lancaster before leaving on 15 June 1945 to also go to Canada.
After the RCAF left in 1945, Croft saw little wartime activity. Later in 1945 the aerodrome became a satellite of No. 13 Operational Training Unit RAF based at Middleton St. George flying de Havilland Mosquitoes. The station was closed in the summer of 1946.  
The Croft aerodrome is now better known as a Croft Circuit, a regular venue for the British Touring Car Championship and British Superbike Championship. It is located near the North Yorkshire villages of Dalton Gates and Dalton-on-Tees.
