Sepulcher Mountain, Mountain summit in Yellowstone National Park, Wyoming, US

Sepulcher Mountain is a peak in the Gallatin Range of the Rocky Mountains, in the northwest of Yellowstone National Park, Wyoming, halfway between Electric Peak and Mammoth Hot Springs. Its summit stands at 9,642 feet (2,939 m), and the Montana state line runs about one kilometre north of it.

The mountain was named in 1871 by Captain John W. Barlow, who saw a resemblance to a crypt in its shape from a distance. The name reflects the visual impression Barlow formed when viewing it from nearby Gardiner, Montana.
