Minyon Falls is a plunge waterfall on Repentance Creek in the Northern Rivers region of New South Wales, Australia.

Dropping more than 100 metres over ancient rhyolite cliffs — remnants of the old Tweed Volcano — it ranks among the most striking waterfalls in northern NSW. The falls sit within Nightcap National Park on the traditional lands of the Bundjalung people.

A popular walking circuit begins at the Minyon Falls car park on Minyon Drive, Whian Whian, leading first to a wheelchair-accessible lookout at the top of the falls, then descending into the gorge through dense rainforest to the base.

The track crosses Repentance Creek via stepping stones and passes small cascades, crystal-clear creeks, and a notable stand of old-growth brushbox trees. An optional side trip to Condong Falls can be added along the way.
