Winterbrook Falls (Lower) is a dramatic waterfall on Winter Brook in northwestern Tasmania, located within the Winterbrook Falls Regional Reserve near Black Bluff Mountain.

The lower falls sit at an elevation of approximately 860 metres, forming part of a larger cascade system that drops a total of around 200 metres off the Black Bluff escarpment in three tiers before the brook eventually joins the Leven River at Loongana.

The lower falls are reached via a Grade 3 return hike of roughly 9–11 kilometres through beautiful myrtle rainforest, with the track following a historical horse-drawn logging tramway. The route is relatively flat for the first 2.

5 kilometres before climbing steeply. A viewing platform roughly 400 metres short of the falls offers a broad outlook across the waterfall and the alpine escarpment above the treeline. The falls are most impressive after rainfall.

Dogs and drones are not permitted on the trail.
