Barton Stacey is a village and undulating civil parish, which includes the hamlets of Bransbury, Newton Stacey, Drayton and Cocum, in the Test Valley district of Hampshire, England, centred about 7 miles (11 km) south-east of Andover. It is bounded to the north by the estate of Drayton Lodge, and, to the south, by the minor A30 road; both being east–west routes, and connected by The Street/Cocum Road, the main road that bisects the village. The distance between the A303 and A30 at this point is 2 miles (3.2 km), which is twice the width of the parish.
