Mathern (Welsh: Matharn; older form: Merthyr Tewdrig) is a village, community, and historic parish in Monmouthshire, south east Wales, about 3 miles (4.8 km) south west of the town of Chepstow, close to the Severn Estuary, the Bristol Channel and the M48 motorway. The village is designated as a Conservation Area. It is now bisected by the motorway, which passes over the road through the village, with the original village located to the south and Newton Green to the north.

Almost adjoining Mathen, and within the community, is Pwllmeyric.
