Royal Air Force Fairford or more simply RAF Fairford (IATA: FFD, ICAO: EGVA) is a Royal Air Force (RAF) station in Gloucestershire, United Kingdom. While being an RAF station, Fairford hosts United States Air Force personnel. Since 2019, the base has played host to a Lockheed U-2S Dragon Lady detachment from the 99th Expeditionary Reconnaissance Squadron. It is the USAF's only European airfield for heavy bombers and routinely supports Bomber Task Force (BTF) operations. Its most prominent use in recent years has been as an airfield for United States Air Force B-52s during the 2003 Iraq War, Operation Allied Force in 1999, and the first Gulf War in 1991.

RAF Fairford was the only TransOceanic Abort Landing site for NASA's Space Shuttle in the UK. As well as having a sufficiently long runway for a shuttle landing (the runway is 3,045 m (9,990 ft) long), it also had NASA-trained fire and medical crews stationed on the airfield. The runway is rated with an unrestricted load-bearing capacity, meaning that it can support any aircraft with any type of load.

RAF Fairford is also the home of the Royal International Air Tattoo (RIAT), an annual air display. RIAT is one of the largest airshows in the world, with the 2003 show recognised by Guinness World Records as the largest military airshow ever, with an attendance of 535 aircraft.
