Barralliers Falls is a waterfall on Christys Creek within Kanangra Boyd National Park, New South Wales, Australia. It drops approximately 149 metres (490 feet), making it one of the more significant falls along this creek system.

Christys Creek descends roughly 1,000 metres over 13 kilometres through deep gorges and dramatic scenery before joining the Kowmung River.

Barralliers Falls sits along a stretch of the creek that requires abseiling to navigate, and trip accounts describe a 35–40 metre abseil anchored from a tree on the right, landing in a pool.

The surrounding terrain is rugged and remote, with slow going through the gorge sections.
