Neath is a town with a population of approximately 60,000, located on the river of the same name in the traditional county of Glamorgan, south Wales. In Welsh, the river is the Afon Nedd, and the town is Castell-Nedd.

Neath has existed as a settlement since Roman times, when the fort of Nidum stood on the spot. Remains of the fort are also still standing, within a housing estate. The actual fort covered an area which now includes the playing fields of Dŵr-y-Felin Comprehensive School. Ruins of a small Norman castle can also be seen, close to the shopping centre.

The previous borough council was adsorbed into the larger unitary authority of Neath Port Talbot on April 1 1996.
