Poonyahra Falls is a waterfall located on the East Branch of Little Nerang Creek within Springbrook National Park, Queensland, Australia.

It sits in the park's Springbrook section, a rugged area known for its concentration of cascades and lush subtropical rainforest. The falls can be visited via a short optional side trip off the Warrie Circuit walking track.

From the junction on the main circuit, a roughly 95-metre path leads to a viewpoint near the falls.

Poonyahra Falls lies in close company with several other named cascades in the area, including Poondahra Falls, Ngarri-dhum Falls, and Goomoolahra Falls, making the broader Warrie Circuit a rewarding route for waterfall enthusiasts.
