The Beaver Dam Mountains Wilderness is a wilderness area located in northwestern Arizona and southwestern Utah, USA, within the arid Colorado Plateau region.

The Wilderness contains some of the lowest elevation land in Utah, and includes a 13 miles (21 km) section of the Virgin River Gorge.

The Mojave Desert landscape of the Beaver Dam Mountains features multitudes of Joshua trees (Yucca brevifolia).

South of Beaver Dam lies the Paiute Wilderness, on the other side of the Interstate 15 corridor and lying partially inside Grand Canyon-Parashant National Monument.
