Pewsham is a small village and former civil parish just south-east of the town of Chippenham on the A4 national route towards Calne in Wiltshire, England.

Although signposted as Pewsham on the main road at both ends, the original settlement does not appear on Ordnance Survey maps, which instead apply the name to the southeastern outskirts of Chippenham.

[1] Spread along the road are a small business centre called Forest Gate, a car dealership and a pub named The Pewsham.

[2] Set back behind the pub is Pewsham House, built in red brick in 1892; it was designed in 17th-century style by the Wiltshire architect Charles Ponting.

[13] The Wilts & Berks Canal, completed in this area in 1797,[14] ran from south-west to north-east, and under a bridge on the A4 near the present-day Hyundai dealership.
