Stonor Park is an historic country house and private deer park situated in a valley in the Chiltern Hills at Stonor, about 4 miles (6.4 km) north of Henley-on-Thames in Oxfordshire, England, close to the county boundary with Buckinghamshire. The house has a 12th-century private chapel. The remains of a prehistoric stone circle are in the grounds. It is the ancestral home and seat of the Stonor family, Baron Camoys.
