(This article is about the medieval priory and later house. For the headquarters of Fighter Command during the Second World War, see RAF Bentley Priory. For the nature reserve, see Bentley Priory Nature Reserve.) Bentley Priory is an eighteenth to nineteenth century stately home and deer park in Stanmore on the northern edge of the Greater London area in the London Borough of Harrow. It was originally a medieval priory or cell of Augustinian Canons in Harrow Weald, then in Middlesex. There are no remains of the original priory, but it probably stood near Priory House, off Clamp Hill.
