Stonor Park is a historic country house and private deer park situated in a valley in the Chiltern Hills at Stonor, about four miles (6.4 km) north of Henley-on-Thames in Oxfordshire, England, close to the county boundary with Buckinghamshire.

Behind the main house, there is a walled garden in an Italianate style on a rising slope, providing good views.

The house was probably begun after 1280 (745 years ago) (1280), when Sir Richard Stonor (1250–1314) married his second wife, Margaret Harnhull.

[2] The Stonor family's steadfast adherence to Roman Catholicism throughout the reformation led to their marginalisation and relative impoverishment in subsequent centuries.

[5] Stonor has been used as a filming location including The Pumaman (1980), The Living Daylights (1987), Danny, the Champion of the World (1989),[6] the final episode of One Foot in the Grave (2000), Endeavour (2019), A Christmas Carol (2019), and Antiques Roadshow (2020).
