Mount Stephen, 3,199 m (10,495 ft), is a mountain located in the Kicking Horse River Valley of Yoho National Park, 1⁄2 km east of Field, British Columbia, Canada.

The Stephen Formation, a stratigraphical unit of the Western Canadian Sedimentary Basin was first described at the mountain and was named for it.

Sometime between this ascent and one in 1892, an estimated 200,000 cubic feet (5,700 m3) of rock had fallen in the upper section of the mountain, making the climb notably easier.

Weather conditions during winter make Mount Stephen one of the better places in the Rockies for ice climbing.
