Hedsor is a small village and civil parish in Wycombe district in Buckinghamshire, England, in the very south of the county, near the River Thames and Bourne End.

[2] The village toponym is derived from the Old English for "Hædde's cliff", referring to the position of the village on a cliff overlooking the Thames.

The modern manor house was built in 1778, and stands on a hill in the village with a commanding view of the Thames and of Berkshire.

In 1583 Rowland Hynd built a new Tudor manor house at Hedsor which was badly damaged by fire in 1795 and eventually demolished in 1865.

At about this time the fourth Lord Boston commissioned the architect James Knowles[clarification needed] to design a new house at Hedsor.
