Cwmyoy is an extensive rural parish in Monmouthshire, Wales (Welsh: Cwm Iou, for the valley and parish; Welsh: Cwm-iou, for the village). The standard Welsh name is Cwm Iau or Cwm-iau. In the Gwentian dialect of Welsh that was spoken here until the late 1800s, the name was pronounced as Cwm Iou ('ou', also spelt informally 'oi', for standard 'au' is a common feature of south Wales Welsh). The 'English' name is in fact this local dialect form in a more English spelling. The name of the valley probably originates from the Welsh word iau meaning yoke, in reference to the shape of the hill surrounding it.The village of Cwmyoy is 7 miles (11 km) north of Abergavenny and 4 miles (6.4 km) south of Llanthony in the Vale of Ewyas in the Black Mountains. It is within the Brecon Beacons National Park, in an upland location just below the broad ridge of Hatterrall Hill, which carries the Wales–England border and Offa's Dyke Path.

The Church of St Martin, Cwmyoy, Monmouthshire, Wales, was begun in the 12th century, although most of the current structure dates from the 13th century. The church is most notable for its extreme tilt, the result of a landslide.

The church is in the Gothic style, and has a chancel, nave, south porch, and western tower. A round-headed north window dates to the 12th century, and the nave roof has been dated to the late 13th or early 14th century. St Martin's is a Grade I listed building and an active parish church.
