Cwm railway station served the village of Cwm in Monmouthshire, Wales.
The station was originally opened by the Monmouthshire Railway and Canal Company on 19 April 1852. It became part of the Great Western Railway in 1880 and remained there at the Grouping of 1923. The line then passed on to the Western Region of British Railways on nationalisation in 1948. The station was closed to passengers by the British Transport Commission on 30 April 1962, remaining open for goods traffic until 4 November 1963.
