Maruia Falls is a 10-metre block waterfall on the Maruia River in the Murchison area of New Zealand's Nelson-Tasman region, accessible from State Highway 65. Its origins are geological rather than ancient: the 1929 Murchison earthquake, a magnitude 7.

8 event, triggered landslides that diverted the Maruia River over a new fault line, carving the falls essentially overnight.

A short, easy track descends from a signposted car park on the Shenandoah Highway to the riverbank, where an open rocky viewpoint offers close-up views of the falls plunging into deep pools below. The falls can be heard before they come into sight.

Swimming and approaching the water's edge are not recommended due to hazardous conditions.
