Sudbrook is a village in Monmouthshire, south east Wales. It is located 4 miles south west of Chepstow and 1 mile east of Caldicot. It lies close to the Second Severn Crossing on the Severn Estuary, and adjoins the village of Portskewett. It was largely built in the late 19th century for workers on the Severn railway tunnel. At that time it was also known as Southbrook.
