The West London derby is the name given to a football derby played between any two of Brentford, Chelsea, Fulham and Queens Park Rangers, all of whom are situated within West London. This particular derby is less prominent than other such derbies in English football, owing to the teams frequently being in separate divisions. Chelsea did not face Fulham between 1986 and 2001, and have played Brentford only seven times since 1950. QPR did not face Brentford between 1966 and 2001, and did not play Chelsea between 1996 and 2008. The derby's most common match, Chelsea vs Fulham, has taken place 75 times. By contrast, the North London derby has been contested almost 200 times, and the Merseyside derby over 230 times.
