Mount Sill is one of the fourteeners of the Sierra Nevada in California. It is located in the Palisades, a group of prominent rock peaks with a few small glaciers on their flanks. Mount Sill is located 0.6 miles (1 km) east of North Palisade, the high point of the group. The two peaks are connected by a high, rocky ridge, on the north side of which lies the Palisade Glacier. Mount Sill lies on the main Sierra Crest, but is at a point where the crest turns sharply, giving it particularly striking summit views. On one side is Kings Canyon National Park and Fresno County; on the other is the John Muir Wilderness, Inyo National Forest and Inyo County.
The mountain is called Nen-i-mish ("the Guardian of the Valley") by the indigenous Northern Paiute people. Its English name was coined, in 1904, by Joseph LeConte, a noted mountaineer, in honor of American poet Edward Rowland Sill.
