Cwmafan (Welsh pronunciationⓘ), also known as Cwmavon, is a large village and community in the Afan valley in Wales, lying within Neath Port Talbot County Borough.

In many ways it is a suburb of the nearby town of Port Talbot which is less than 2 miles (3 km) to the south.

West of Foel Fynyddau is Mynydd-y-Gaer: at its summit the community boundaries of Cwmafan, Baglan and Briton Ferry all meet.

The metal ores, from as far away as Chile, were off-loaded in Port Talbot or Swansea docks and brought by rail to Cwmafan.

[3] A resident of Maesteg, Paul Barry, escaped unharmed from the incident, despite being on the bridge when it collapsed.
