Froxfield is a village and civil parish in English county of Wiltshire on the border with West Berkshire. It lies directly on the Wiltshire-West Berkshire border, situated on the A4 national route 3 miles (4.8 km) west of Hungerford and 7.5 miles (12 km) east of Marlborough.
Froxfield village is on a stream that is a tributary of the River Dun. The road between London and Bristol follows the valley of the stream and passes through the village. The road has followed this course since at least the 13th century and since the 1920s has been classified as the A4 road.
The Kennet and Avon Canal follows the Dun valley through Froxfield parish, passing within of the village. The canal has a series of locks in the parish from Oakhill Down Lock to Froxfield Bottom Lock. The Reading to Taunton railway line also follows the river through the parish below the village.
