Redbrook is a village in Gloucestershire, England, adjoining the border with Monmouthshire, Wales.

Both Upper and Lower Redbrook were mentioned in the Domesday Book of 1086 as lying within the hundred of Bromsash and they were both listed under Gloucestershire and Herefordshire.

The railway was opened in 1876 to connect Monmouth to the South Wales line, closing to passengers in 1959 and freight in 1964.

The Boat Inn is accessed from Redbrook via Penallt Viaduct, which used to carry the Wye Valley Railway across the River.

The Offa's Dyke Path and the Wye Valley Walk run through the village.
