Wanderers Football Club was a pioneering English football team, instrumental in the early development of association football. Founded in 1859 as Forest Football Club in Leytonstone, London, it was renamed Wanderers in 1864 to reflect its lack of a fixed home ground, playing matches at various locations across London.

Comprising mainly former public school pupils, especially from Harrow School, Wanderers became one of the dominant teams in the early years of organised football. They were among the founding members of The Football Association in 1863 and played a significant role in shaping the modern game. Notably, they won the inaugural FA Cup in 1872 and went on to secure the trophy five times in total, including three consecutive wins from 1876 to 1878—a feat that has been matched only once since, by Blackburn Rovers.

Prominent figures associated with the club include C. W. Alcock, often referred to as the "father of modern sport," and Arthur Kinnaird, considered one of the greatest players of his era. However, by the 1880s, the club's prominence declined as other teams emerged, and many of its players joined clubs affiliated with their former schools. Wanderers eventually dissolved around 1887.​

In 2009, a club bearing the name Wanderers F.C. was re-established in London, initially for a fundraising match. This modern incarnation competes in the Surrey South Eastern Combination and claims approval from descendants of some original Wanderers players
