Bovingdon is a village in Hertfordshire, England, four miles southwest of Hemel Hempstead, and it is a civil parish within the local authority area of Dacorum. It forms the largest part of the ward of Bovingdon, Flaunden and Chipperfield, which had a population of 4,600 at the 2001 census, increasing to 9,000 at the 2011 Census.

The name is first mentioned in deeds from 1200 as Bovyndon. It could originate from Old English Bufan dune meaning "above the down" or from Bofa's down, the down belonging to Bofa.

What used to be the Bobsleigh Inn on Box Lane, just east of the village, is a large house with some parts dating to the sixteenth century. It used to be a hotel and restaurant. It was the Bovingdon Country Club until 1964 when Tony Nash, the son of the owner, was part of the gold medal winning British two-man bobsleigh team at the Winter Olympics at Innsbruck in Austria. It was renamed the Bobsleigh Inn in his honour. During World War 2 many celebrities stayed at the Country Club while entertaining troops at the airfield, including Bob Hope, James Stewart and Glenn Miller.

Next to Bovingdon is the disused former World War II, Eighth Air Force and post-war Royal Air Force airfield, RAF Bovingdon. The airfield was built in 1942. Between 1943 and 1946 it became a B-17 operational training base for units such as 92nd Bomber Group, B-17 Flying Fortress Combat Crew Replacement Centre (CCRC), 11th CCRC, and 8th USAAF HQ Squadron. The RAF resumed control until 1951, then the USAF took over again until 1962 flying B-26 Marauders, B-29 Superfortresses, and B-50 Superfortresses. General Dwight D. Eisenhower's personal aircraft was said to be located here, as Bovingdon was the closest Eighth Air Force airfield to London.

Flying ceased in 1969, though some flying scenes for the film Hanover Street were shot there in 1978. The airfield served as airport for Hemel Hempstead during most of the postwar period.

Several films have been made there including The War Lover, 633 Squadron, Hanover Street, an episode of The Persuaders!, The Man with the Golden Gun (the flying car scene), Mosquito Squadron, and the Live Aid recreation in the film Bohemian Rhapsody.

The airfield site houses a VOR navigational beacon, code BNN. The airspace above the airfield and nearby Chesham is known as the Bovingdon stack and is a holding area for aircraft approaching Heathrow Airport, 20 miles to the south. At busy times on a clear day a dozen planes circle.

Part of the airfield was used to build The Mount Prison during the 1980s; it was located on the site of the aircraft hangars and administration blocks. The remainder of the site is used for a Saturday market and there is a permanent circuit for banger racing although there has not been any regular racing since 2008. The airfield is also a site for paintballing and in more recent years, ITV Studios Bovingdon.

Of the three original runways, the North East/South West runway is still complete, and used for parking on market days. The North West/South East runway is completely gone. The East/West runway is still complete, the Eastern end of which is used for the weekend Market, the Western end used to be used by the Farmers aircraft. The control tower still exists, but is in a very poor state. A lot of the taxiways, and the 2nd World War Bomb Dump trackways are mostly gone, a victim of hardcore reclamation, a common end of a large number of disused airfields in the UK.

In 1971 the poisoner Graham Frederick Young committed two murders while working for a local photographic company, John Hadland.

The village has a historical society, 'The Bovingdon History Group', who host regular talks on items of local interest, which are held at the Baptist Church.
