Battery Falls is a waterfall on the Little Nymboida River in northern New South Wales, located roughly 12 kilometres northwest of Ulong.

It sits within a steep rainforest setting and is accessible via a short trail — approximately 250 metres down a faint, steep track from Battery Road.

The falls are well regarded by whitewater paddlers as a Grade IV+ "park-and-huck" drop, considered one of the closest things to a classic plunge waterfall found on the plateau.

The surrounding section of the Little Nymboida is a technical, seldom-paddled run with pools and rocky drops.

For non-paddlers, a carpark off Battery Road provides access to the walking trail, and an informal riverside campsite lies about a kilometre further along the road.
