Pwll Berw is a plunge pool and waterfall feature on the River Sychryd within the Sychryd Gorge, located near Pontneddfechan in the Bannau Brycheiniog (Brecon Beacons) National Park, South Wales. It sits at approximately SN 91639 08009.

The feature is formed by Sychryd Waterfall, a three-tiered cascade that flows beneath a wooden footbridge and empties into the emerald plunge pool of Pwll y Berw.

The gorge setting is dramatic, with quartzite crags forming a natural amphitheatre around the falls. A short trail from the Dinas Rock car park leads visitors down a stepped path to the river, where the bridge and waterfall come into view.

The site lies close to the Sychryd Cascades and is part of the wider Waterfall Country walking network.
