No. 90 (Composite) Wing was a Royal Australian Air Force (RAAF) wing that operated during the early years of the Malayan Emergency. It administered two RAAF units, No. 1 (Bomber) Squadron, flying Avro Lincolns, and No. 38 (Transport) Squadron, flying Douglas C-47 Dakotas. The wing was termed "composite" because it operated a mixed complement of aircraft, rather than only one type. Following No. 38 Squadron's departure for Australia in December 1952, No. 90 Wing was disbanded, leaving No. 1 Squadron to carry on as the sole RAAF unit in the campaign until its withdrawal in July 1958.
