Uppingham School is a public school in Uppingham, Rutland, England, founded in 1584 by Robert Johnson, the Archdeacon of Leicester, who also established Oakham School. The headmaster, Richard Maloney, belongs to the Headmasters' and Headmistresses' Conference and the school to the Rugby Group of British independent schools. Edward Thring was the school's best-known headmaster. His curriculum changes were adopted in other English public schools. John Wolfenden, headmaster from 1934 to 1944, chaired the Wolfenden Committee, whose report recommending the decriminalisation of homosexuality appeared in 1957. Uppingham has a musical tradition based on work by Paul David and Robert Sterndale Bennett. It has the biggest playing-field area of any school in England, in three separate areas of the town: Leicester to the west, Middle to the south, and Upper to the east.

In England and Wales, a public school is a type of fee-charging private school originally for older boys. They are "public" in the sense of being open to pupils irrespective of locality, denomination or paternal trade or profession; nor are they run for the profit of a private owner.
