Brompton (Welsh: Brontyn) is a hamlet in Shropshire, England. It lies on the A489 between Church Stoke and Newtown (both in Powys) at its junction with the B4385. The hamlet is notable for the fact that it is impossible to reach any other settlement in England (except Pentreheyling) by road without first passing through Wales. Public footpaths are the only access which links it with the rest of England. It is, however, not geographically an exclave. It is also notable as having Welsh language road signage on the B4385 heading south into Powys, unique in England.
