Bryn (English: Hill) is a village and community in Neath Port Talbot County Borough in Wales. It has a population of 913. The village is located in the hills between Cwmafan, in the Afan Valley, and Maesteg in the Llynfi Valley, approximately 6 miles (9.7 km) from Port Talbot and 2 miles (3.2 km) from Maesteg. The name of the village now familiarly 'Bryn', is Bryntroedygam. So wrote the first vicar of St Theodore's in Port Talbot. There was a farm situated above Meadow Row named Bryn-Troed-y-Garn as shown on the 1876 OS map, as many more immigrants came to 'Bryntroedygam' it seemed the name of the village was to be shorted to Bryn. 12% of the village speak Welsh. The population rose to 923 by 2011.

Cwmafan, sometimes known as Cwmavon in English, is a large village and community in the Afan valley in Wales, lying within Neath Port Talbot County Borough. It had a population of 5,603 in 2001, increasing slightly to 5,615 at the 2011 Census. Cwmafan is known for having a high percentage of Welsh speakers. 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. The literal translation of Cwmafan from Welsh to English is complex, Cwm means valley with Afan as the name of the river flowing through, hence the village residing within the Afan Valley. It could be a version of Afon which means river, so literally the "River Valley", this is common in Wales and the UK with many rivers being called Afon or Avon. There is also a Saint Afan, which it is possible the river was named after. There have been other suggestions but none accepted locally.
