Bulwark is a predominantly residential area of Chepstow, Monmouthshire, Wales, largely developed during the twentieth century.

The area was predominantly in agricultural use until the twentieth century, with farms including Claypits, St Tecla, and Burnt Barn.

The area south of the A48 Newport Road contains a number of large 19th-century villas which were on the outskirts of Chepstow when built, and commanded extensive views eastwards towards Sedbury.

Nearby, on the road towards Mathern, Chepstow Cemetery was established in 1855, after the town's churchyard was deemed to be overcrowded; it received its first burials two years later.

[4] Bulwark Garden Suburb was developed between 1917 and 1919, as housing for the workers at the National Shipyard which was established during the First World War south-east of the railway line at Chepstow.

A shopping area developed on Bulwark Road, and the Severn Bridge Social Club (closed in 2019)[6] was opened on the site of the former Claypits Farm in 1965.

Bulwark was also the childhood home of Richard William Church (1815-1890), Dean of St Paul's Cathedral and writer.
