Williams Falls is a dramatic 40-metre waterfall on the Williams River, located in the Barrington Tops region of mid-New South Wales, roughly three hours north of Sydney.

The river flows south from the Barrington Tops plateau, and the falls plunge into a striking natural amphitheater below.

The waterfall is reached via a committing journey that begins at Lagoon Pinch on the south side of Barrington Tops, climbing over 600 vertical metres to the plateau before descending steeply through rainforest via Ki Gully.

Most parties travelling the Williams River canyon access the falls from above, with many choosing to bypass the drop itself via a circuit walk around the true left rather than abseiling the falls directly.
