Fulham Football Club is an English professional association football club based in Fulham, London who currently compete in the Premier League. Founded in 1879, they are London's oldest professional football club.

The club has spent 27 seasons in English football's top division, the majority of which have come in two periods during the 1960s and 2000s. The latter period was associated with former chairman Mohamed Al-Fayed, after the club had climbed up from the fourth tier in the 1990s. Fulham have reached two major finals: in 1975 they lost 2–0 against West Ham United in the FA Cup Final as a Second Division team, and in 2010 they played Atlético Madrid in the UEFA Europa League Final, losing 2–1 after extra time.

Fulham's main rivalries are with fellow West London clubs Chelsea, Queens Park Rangers and Brentford. The club adopted a white shirt and black shorts as its kit in 1903, which has been used ever since.

Fulham were formed in 1879 as Fulham St Andrew's Church Sunday School F.C., founded by worshippers (mostly adept at cricket) at the Church of England on Star Road, West Kensington (St Andrew's, Fulham Fields). Fulham's mother church still stands today with a plaque commemorating the team's foundation. They won the West London Amateur Cup in 1887 and, having shortened the name from Fulham St Andrews to its present form in December 1888, they then won the West London League in 1893 at the first attempt. One of the club's first ever kits was half red, half white shirts with white shorts worn in the 1886–87 season. Fulham started playing at their current ground at Craven Cottage in 1896, their first game against now defunct rivals Minerva. Fulham are one of the oldest established clubs in southern England currently playing professional football, though there are many non-league sides like Kent side Cray Wanderers who are several decades older.
