Unicorn Peak, Granite summit in Tuolumne County, US.

Unicorn Peak is a granite summit in Yosemite National Park that rises to 10,823 feet and features three distinct spires, with the northern point reaching the highest elevation. The rock formation displays sharp, jagged edges that are especially visible from Tuolumne Meadows below.

The peak was named during the Whitney Survey of 1863 because of its characteristic horn-like shape visible from the surrounding highlands. During the Tioga glaciation, it remained exposed above the ice as a nunatak while glacial forces carved the landscape around it.

The peak's name comes from its horn-like profile, which the Whitney Survey of 1863 recorded. Today most visitors see it from Tuolumne Meadows or the Cathedral Lakes trail rather than climb it; the easiest route to the summit is a class 4 rock climb, and hikers often stop at the base or at nearby Budd and Elizabeth lakes.

The easiest route to the summit is a class 4 rock climb; other routes exist on the peak. Many visitors hike only to the base of Unicorn Peak and to nearby sites such as Budd Lake, Elizabeth Lake and Cathedral Peak. The peak lies due east of Cathedral Peak in the Cathedral Range, above Tuolumne Meadows.

Unicorn Peak is one of three peaks in the Cathedral Range—with Cathedral Peak and Cockscomb Peak—that stood as nunataks above the Tioga glaciation ice. The glaciers sharpened the bases of the peak and plucked at its sides, leaving the summit standing free of the ice sheet.
