The East London derby is a football match that takes place between two of either Dagenham & Redbridge, Leyton Orient and West Ham United. This derby rarely takes place because, as is the case with the Dockers Derby, the clubs are usually in different leagues.
The last time West Ham United and Leyton Orient shared a competitive meeting was on 31 January 1987 in the FA Cup which West Ham won 4–1 with their goals coming from McAvennie, Cottee, Keen and Parris. West Ham and Dagenham & Redbridge have never met since the latter was formed in 1992 from the merger of Redbridge Forest and Dagenham. However, Leyton Orient and Dagenham & Redbridge meet occasionally in the lower leagues. They played each other in League Two in the 2015–16 season, with Leyton Orient winning both matches.
