Leytonstone F.C. was an English football club based in Leytonstone, Greater London. Founded in 1886, the club ceased to exist in 1979 when it merged with Ilford to form Leytonstone-Ilford, which later became Redbridge Forest after also absorbing Walthamstow Avenue. Redbridge Forest in turn merged with Dagenham to form the modern Dagenham & Redbridge.
