No. 38 Group RAF was a group of the Royal Air Force which disbanded on 31 December 2020. It was formed on 6 November 1943 from the former 38 Wing with nine squadrons as part of Transport Command. It was disbanded on 31 January 1951, but re-formed on 1 January 1960, became part of RAF Air Support Command in 1967 and then, in 1972, the air support group within RAF Strike Command. It was temporarily disbanded from 18 Nov 1983 to 31 Oct 1992 and from 1 April 2000 to 1 July 2014. It subsequently became part of RAF Air Command, bringing together the Royal Air Force’s Engineering, Logistics, Communications and Medical Operations units. Air Officer Commanding No. 38 Group was also responsible for UK-based United States Visiting Forces (USVF) units and for RAF personnel attached to other global armed forces.

Air Support Command of the Royal Air Force was formed on 1 August 1967 by the redesignation of Transport Command. Its change of name reflected the change of emphasis of the Command from solely transporting materials and manpower around the world to providing general support to RAF operations around the world.
