London Biggin Hill Airport, formerly RAF Biggin Hill, is an airfield at Biggin Hill in London Borough of Bromley.

It opened in 1917 as a communications base, and was later a Royal Air Force airbase during the Battle of Britain during the Second World War. After the war it became a small-scale civilian airport, and has continued as such. There is an ongoing dispute about whether scheduled passenger services should be allowed to use the airport.
