Wheeler Peak Wilderness, Protected wilderness area in Carson National Forest, New Mexico.

Wheeler Peak Wilderness covers 19,661 acres (7,957 ha) in the Carson National Forest and holds Wheeler Peak, at 13,161 feet (4,011 m) the highest point in New Mexico, plus Williams Lake. Its slopes rise from cottonwood and bristlecone pine stands through Engelmann spruce and subalpine fir to open alpine tundra above the treeline.

The area received federal protection in 1964 through the Wilderness Act and underwent boundary expansion in 1980. Additional land transfers in 1996 reinforced its protected status.

The wilderness lies within the traditional territory of Taos Pueblo, and in 1996 Public Law 104-333 transferred 764 acres south of the ridge between Simpson Peak and Old Mike Peak, west of Blue Lake, to the pueblo. The name honors Wheeler Peak, the state's highest summit at 13,161 feet.

Visitors access the area through maintained trails from highways NM 150 or NM 578, with the Williams Lake Trail and Wheeler Peak Trail serving as main routes. Weather and elevation significantly affect conditions, so planning ahead is important.

Bighorn sheep were native to the Wheeler Peak Wilderness but were re-introduced there in 1993; the animals seen on the high slopes today descend from that effort. The wilderness also holds Williams Lake, and its rivers and alpine lakes are stocked every few years with cutthroat and rainbow trout by the New Mexico Department of Game and Fish.
