Beauchamp Falls is a plunge waterfall on Deppeler Creek in the Otway Ranges, near the locality of Beech Forest in Victoria, Australia. It drops approximately 18.

7 metres (61 ft) in a single tier and is most likely named after New Zealand-born engineer George Fox Beauchamp-Proctor, who oversaw construction of the Beech Forest railway.

The falls are reached via a moderate, roughly 3–4 km return walk that descends steeply through mountain ash forest and lush rainforest ferns. A lower lookout provides a clear view of the cascade.

The track has steep, potentially slippery sections and is not accessible to wheelchairs or prams. A campground near the trailhead serves as a popular base for visitors exploring this corner of the Great Ocean Road hinterland.
