The Lydden Hill Race Circuit is a small but perfectly formed racetrack between Dover and Canterbury, in the British county of Kent. It is one mile (1.609 kilometres) long, making it the shortest asphalt circuit in Great Britain - short but sweet, however. The many undulations make Lydden Hill an extremely challenging circuit.

The facility was opened in 1955 and was initially designed for stock car and grass track races. Ten years later, the asphalted racetrack was built, on which car races up to Formula 3 could be staged. In the 1990s, McLaren bought the Lydden Hill Race Circuit and planned to convert it into a Formula One test track. They were not granted the necessary approval, however. Instead, the site is now primarily used for rallycross events. Lydden Hill is also a popular venue for touring car, sports car and motorbike races.
