Upton is a hamlet in the parish of Dinton-with-Ford and Upton, in Buckinghamshire, England. It is located to the north of the main village of Dinton, on the junction between the new road from Aylesbury to Thame, and the old road before it was rerouted.
The hamlet name is a common one in England, and means 'higher farm', referring in this case to the hamlet's location at the top of an adjacent hill to Dinton.
The hamlet is often confused with the village of Upton, Slough, which is now a suburb of the unitary authority of Slough in Berkshire, formerly also in Buckinghamshire.
