Leyton Football Club was an English association football club based in Leyton, in the London Borough of Waltham Forest. The club withdrew from the Isthmian League Division One North in January 2011 due to severe financial difficulties, and disbanded. The first club to go by the name was founded in 1868, and the last incarnation of the club, which began playing in 1997, won a High Court action in 2002 in support of its claim to be a continuation of the original team, making it at that stage the second oldest existing club in Greater London, after Cray Wanderers.
