Billy Brown's Falls is a waterfall located on Judds Creek in the Russell Ridge Conservation Area near Judbury, Tasmania, roughly an hour west of Hobart. It is regarded as more impressive than nearby Judds Falls and is a popular day-walk destination.

Access begins along Judds Creek Road out of Judbury. The road is manageable for most of the drive, but the final few kilometres beyond a culvert over Judds Creek become rough, with large potholes and rocks.

A 4WD is strongly recommended; drivers in standard vehicles should park at the culvert and walk the remaining 3. 5 km each way along the road, adding at least two hours to the trip.

The hike itself is rated Grade 3, with a formed earthen track requiring some bushwalking experience.
