Pontneddfechan (Welsh for 'bridge over the Little Neath'; pronounced [pɔntˌniðˈvɔːn]; also known as Pontneathvaughan) is a village in Powys, Wales. It is the southernmost village in the historic county of Brecknockshire, within the Vale of Neath and in the community of Ystradfellte. It stands at the confluence of the rivers Mellte and Nedd Fechan ("Neath Vaughan") and gives access to a series of waterfalls that adorn the upper Neath valley. Dinas Rock is a quarried limestone promontory east of the village, popular with visitors.
