The Caerfanell is a river which rises in the central section of the Brecon Beacons National Park in Powys, Wales. It rises as Blaen Caerfanell on the plateau of Gwaun Cerrig Llwydion and drops steeply down south-eastwards into the head of Glyn Collwn before turning east then north-east into Talybont Reservoir. It emerges from the hydro turbine beneath the dam just above the village of Aber and continues northwards to its confluence with the River Usk at the hamlet of Llansantffraed.

Its principal tributaries are the Nant Bwrefwr, Nant Tarthwynni, Clydach and Cwy.[1]
