The Mount Massive Wilderness is a federally designated wilderness area in the Sawatch Range, located in the U.S. state of Colorado. It is operated jointly by the United States Forest Service and the Fish and Wildlife Service as part of the San Isabel National Forest and the Leadville National Fish Hatchery.
