Westwood is a large village and a civil parish in west Wiltshire, England. The village is about 1.4 miles southwest of the town of Bradford-on-Avon. Upper Westwood, on a ridge crest to the north, was a distinct settlement from Lower Westwood but 20th-century housing filled the gap. The parish includes most of the village of Avoncliff, namely the portion south of the Avon, and the hamlet of Lye Green.
