The East London derby[1] is a football match that takes place between any two of Dagenham & Redbridge, Leyton Orient and West Ham United.

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.

However, Leyton Orient and Dagenham & Redbridge meet occasionally in the lower leagues.

There is very little current rivalry between Leyton Orient and West Ham, mainly because they have been in different divisions for over 41 years.

A total of 13 matches have been played to date with Orient having the upper hand with six victories against five for Dagenham, with two games ending in a draw.
