Royal Air Force Hullavington, or more simply RAF Hullavington, (ICAO: EGDV) was a Royal Air Force station located at Hullavington, near Chippenham, Wiltshire, England. The station opened in June 1937 and was primarily used for training. It closed on 31 March 1992 when it was transferred to the British Army and renamed Buckley Barracks. The airfield part of the site, known as Hullavington Airfield, continued to be used for RAF gliding operations until 2016 when it was sold to technology company Dyson.

The site spans three parishes: the hangars and grassland in the north and west lie in Hullavington parish, while other hangars, most of the runways and the northern part of the barracks are in St Paul Malmesbury Without. The rest of the barracks are in Stanton St Quintin parish and are near the small village of Lower Stanton St Quintin and the A429 Chippenham-Malmesbury road.

The airfield was opened on 14 June 1937 with No 9 Flying Training School arriving from RAF Thornaby on 10 July. Leonard Cheshire V.C. trained here in 1939. With the beginning of the Second World War, top officers from allied nations came to Hullavington to share ideas and methods. Ten Blenheims from No 114 Squadron arrived at the base on 1 September 1939, and were later joined by seven from No 139 Squadron. This was a safety move as a sustained attack was expected at the East Anglian bomber bases on the announcement of war. As this didn't happen, all the Blenheims departed Hullavington by 16 September 1939. An effective Met. Office was also stationed at Hullavington, and an aircraft left every day at dawn to gather weather data at various altitudes.

In 1970, RAF Hullavington hosted the World Aerobatic Championships.

In 1992, the entire airfield was designated a conservation area. English Heritage (now Historic England) later stated that "It embodies, to a unique degree, the improved architectural quality associated with the post-1934 expansion of the RAF. Most of the original buildings have survived and form a particularly coherent and well-ordered ensemble." Grade II listed buildings include the officers' mess and the church.

In 1993, a Senior Aircraftman was convicted of arson and sent to jail for 5 years and his accomplice received a fine of £1000. The hangar was the location of all the parachutes for the armed services, and the damage and loss of stock affected morale at the base.

The station has performed many roles, summarised with dates below.

The Defence Codification Data Centre (DCDC) lodged in a purpose-built computer suite at RAF Hullavington from its establishment in 1966 until its dispersal to Glasgow in 1986, where it merged with its parent body, the Defence Codification Authority.^{[citation needed]}
