Steavenson Falls is a striking waterfall on the Steavenson River, located about 4 kilometres southeast of Marysville in Victoria, Australia.

One of the tallest waterfalls in the state, it descends a total of 122 metres over five cascades, with the final drop falling more than 21 metres in a clear plunge.

Both the falls and the river were named after John Steavenson, Victorian Assistant Commissioner for Roads and Bridges, who surveyed the area in 1862. A track to the falls was cut in 1866, and the site has drawn visitors ever since.

The forested catchment ensures a year-round flow. Notably, the falls are floodlit after dark, powered by electricity generated by the falls themselves, offering a distinctive nighttime viewing experience found nowhere else in Victoria.
