Denville Hall is a historic building in Northwood, a town in the London Borough of Hillingdon, England, which is used as a retirement home for professional actors, actresses and members of other theatrical professions. The present building incorporates part of a 16th-century house, which was substantially rebuilt in 1851 and later considerably extended after becoming a retirement home in 1926. Many well-known British actors and actresses have lived there.
