Denman, formally Denman College, was a residential adult education college centred on what was Marcham Park at Marcham in the English county of Oxfordshire (formerly Berkshire). Founded by the National Federation of Women’s Institutes (NFWI) in 1948, Denman offered day schools and residential courses in cookery, craft and lifestyle, as well a variety of events, conferences and weddings. In July 2020 the NFWI trustees announced the proposed permanent closure of the college.
