Multnomah Falls is a waterfall on the Oregon side of the Columbia River Gorge, located east of Troutdale, between Corbett and Dodson, along the Historic Columbia River Highway.

The falls drops in two major steps, split into an upper falls of 542 feet (165 m) and a lower falls of 69 feet (21 m), with a gradual 9 foot (3 m) drop in elevation between the two.

Underground springs from Larch Mountain are the year-round source of water for the waterfall, augmented by spring runoff from the mountain's snowpack and rainwater during the other seasons.
