Wellington College is a British co-educational boarding and day independent school in the village of Crowthorne, Berkshire. Wellington is a registered charity (#309093) and currently has about 1,050 pupils aged between 13 and 18. It was built as a national monument to the first Duke of Wellington (1769–1852), after whom the College is named. Her Majesty Queen Victoria laid the foundation stone in 1856 and inaugurated the School's public opening on 29 January 1859.

Many former Wellington pupils fought in the trenches straight after leaving school during the First World War, volunteering for military action, a conflict in which 707 of them lost their lives. A further 501 former pupils were killed in action in the Second World War.

The school is a member of the Rugby Group, which includes Harrow School and Charterhouse School, and is also a member of the G20 Schools group. The Good Schools Guide calls the school "a serious player in the field of education".
