Chapel House, Hereford Road, Monmouth, Wales, is a Georgian townhouse, built in the early eighteenth century, described by the architectural historian John Newman, as "the best house in the entire street".

The house, originally called The Chantry, then St Brides, is substantially of the early eighteenth century.

The windows were replaced and a new entrance doorway was added around 1800, probably by ironmaster David Tanner.

Chapel House was restored in 1910 by Humphrey Farran Hall who repaired the panelling.

When it was reroofed in the later twentieth century, the large chimney stacks were removed.
