Liffey Falls is a series of four tiered-cascade waterfalls on the Liffey River, situated in the Midlands region of Tasmania, Australia, within the Liffey Falls State Reserve.

The falls drop a combined 120–160 metres (390–520 ft) at an elevation of around 514 metres, and the reserve forms part of the Tasmanian Wilderness World Heritage Area.

The river collects water from the Great Western Tiers, and as it flows downslope, erosion of softer mudstone exposes sandstone steps that create the cascading sequence.

The largest and most photographed of the four drops — officially named Victoria Falls but commonly called Liffey Falls — is flanked by ferns and temperate rainforest vegetation. Two small pools sit below it, separated by a wide cascade.

Trails from both an upper and a lower car park wind through the rainforest to reach the falls, with the upper-car-park route being the shorter and more developed path. The reserve lies roughly an hour's drive from Launceston.
