Addington is a village in Buckinghamshire, United Kingdom, about 2 miles west of Winslow and 3 miles south east of Buckingham.

First recorded as Edintone in the Domesday Book of 1086, its name means Eadda's Estate. Nearby Adstock is named after the same person. The manor at that time was in the possession of Odo, Bishop of Bayeux.

A notable building in the village is the Mansion House, which is a 19th century building on the site of the much older manor. The former manor house was used twice during the English Civil War as the national headquarters of the Parliamentarian forces.

The parish church is dedicated to St. Mary the Virgin.
