Emigrant Wilderness, Protected wilderness area in Tuolumne County, California.

Emigrant Wilderness is a glaciated wilderness area of Stanislaus National Forest in the Sierra Nevada, about 25 miles long and up to 15 miles wide. Its northeastern third is dominated by volcanic ridges and peaks, while the rest consists of sparsely vegetated granitic ridges interspersed with lakes and meadows. Elevations run from below 5,000 feet near Cherry Reservoir to 11,570 feet at Leavitt Peak.

Native peoples used the high country for summer and autumn hunting for 10,000 years before the Sierra Miwok and Paiute were the most recent groups there. In September–October 1852 the Clark-Skidmore party became the first emigrant group to travel the West Walker route over Emigrant Pass through part of today's wilderness. Officials from Sonora drew more parties to the route in 1853, but hardships led to its abandonment; Relief Valley and Relief Reservoir recall aid given by Sonora residents. In 1931 the Forest Service designated the Emigrant Basin Primitive Area, redesignated Emigrant Wilderness on January 4, 1975.

The most recent native groups here were the Sierra Miwok of the western slope and the Paiute of the Great Basin, who spent summers and early autumn hunting in the high country and trading with groups from the eastern side of the Sierra Nevada. This use ended after gold was found in 1848, when miners and settlers arrived and native cultures quickly declined.

Access to the area is available through multiple trailheads located near Pinecrest, where paths lead into the wilderness. The Pacific Crest Trail runs along the eastern boundary and offers connections to other mountain regions.

Anglers built the 18 small dams by tightly stacking nearby stones and boulders, not with concrete. A 2006 court ruling overturned a Forest Service compromise that would have kept some dams maintained, and the agency chose not to appeal, so the dams will gradually disappear.
