The Clarendon Institute (or the Clarendon Press Institute) is a building in Walton Street, central Oxford, England. In 1891, Horace Hart (1840–1916) of the Clarendon Press (now Oxford University Press) proposed an institute to provide a place providing relaxation and further education facilities for staff at the Press. He planned a gymnasium, library, and reading room, and to provide teaching of French, German, Greek, Latin, mathematics, and shorthand. The building was designed by H. W. Moore and built during 1892–93. It cost £5,000 to build. In 2016, the building suffered a fire.
