Ngarigoon Falls (also spelled Nagarigoon) is a small but scenic waterfall on Nixon Creek in the Binna Burra section of Lamington National Park, southeast Queensland.

Its name derives from the Yugambeh word for "playfulness," a fitting tribute from the traditional custodians of this region.

Although the drop is modest, the falls sit within a shaded, grotto-like setting framed by towering subtropical rainforest, making it a highlight for many visitors.

The waterfall is reached via a short optional side track off the Ships Stern Circuit, accessible from the Border Track and Daves Creek Circuit.

It can be visited as part of the full 19–21 km Ships Stern Circuit or as a shorter out-and-back walk from the upper car park near the Binna Burra café. Walkers heading to Upper Ballunjui Falls often pass Ngarigoon Falls along the way.
