Hon. Sir William Stanhope (1702–72), of Eythrope, Buckinghamshire, was an English landowner and opposition Whig politician, who sat in the House of Commons for 35 years between 1727 and 1768. Afflicted with deafness and ill-health, he travelled frequently and was often absent from Parliament.

Eythrope is a hamlet and country house in the parish of Waddesdon, in Buckinghamshire, England. It is located to the south east of the main village of Waddesdon. It was bought in the 1870s by a branch of the Rothschild family, and belongs to them to this day.
