Aberavon is a town and community in Neath Port Talbot county borough, Wales. The town derived its name from being near the mouth of the river Afan, which also gave its name to a medieval lordship. Today it is essentially a district of Port Talbot, covering the central and south western part of the town. Aberavon is also the name of the nearby Blue Flag beach and the parish covering the same area.

The River Afan is a river in Wales whose valley formed the territory of the medieval Lords of Afan. The Afan Valley encompasses the upper reaches of the river. The valley is traversed by the A4107 road. Settlements in the area include Cwmafan, Pontrhydyfen and Cymmer. The town of Aberavon, whose name in Welsh Aberafan means 'mouth of the Afan', grew up on the banks of the river and was later subsumed by the town of Port Talbot.
