Cefn-coed-y-cymmer (pronounced [ˌkɛvɛnˌkɔi̯dəˈkəmɛr]) is a small community on the northwestern edge of Merthyr Tydfil County Borough in Wales. It is situated in the neck of land between the rivers Taf Fawr and Taf Fechan at their confluence (Welsh: 'cymer'). The village lies within the community of Vaynor. Immediately to the north of the village is the hill of Cefn Cil Sanws on the southern slopes of which is Merthyr Tydfil Golf Club. The village is bounded both to the north and the west by the Brecon Beacons National Park.Notable features of the village are the A465 Heads of the Valleys Road and the impressive curving Cefn Coed Viaduct. The viaduct, which spans the Taf Fawr river, came into being as part of the Merthyr- Pontsticill junction line. This additional line extended the Brecon and Merthyr Railway and was only agreed following a special Act of Parliament in July 1862 to allow its construction. The Cefn Coed Cemetery with its Jewish burial ground is listed on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales.

Vaynor and Penderyn High School was situated at Cefn Coed, Merthyr Tydfil in Wales. Although now part of Merthyr Tydfil, the area covered by the school was part of the old county of Brecknockshire (Breconshire) until local government reorganisation in 1974. The designated catchment area of the school was made up of the communities served principally by Ysgol y Graig Primary in Merthyr Tydfil and Penderyn and Hirwaun Primary Schools in Rhondda Cynon Taff, and is an area which suffers a high degree of economic deprivation. The school had an age range of 11-18 and a capacity of 455 places which would be small for a secondary school even if full. The School was opened by Robert Crawshay in 1861 but closed in 2005.

Llwyn-on Reservoir (or Llwyn Onn Reservoir) is the largest and southernmost of the three reservoirs in the Taf Fawr valley in South Wales. Cardiff Corporation Waterworks obtained an Act of Parliament in 1884 to authorise construction of the reservoirs, to increase the water supply for Cardiff, but construction of Llwyn-on Reservoir did not start until 1911 and was completed in the 1920s. The reservoir, which has been owned and managed by Welsh Water and its predecessor organisation, the Welsh Water Authority, since 1973, is located within the Brecon Beacons National Park with its eastern half in the Merthyr Tydfil unitary authority area and the western half in Rhondda Cynon Taf. The village of Llwyn-On is nearby and the A470 trunk road runs along its eastern shoreline.
