List of wilderness areas of the United States

The National Wilderness Preservation System includes 806 wilderness areas protecting 111,889,002 acre of federal land. They are managed by four agencies:


 * National Park Service (NPS)
 * United States Forest Service (USFS)
 * United States Fish and Wildlife Service (FWS)
 * Bureau of Land Management (BLM)

These wilderness areas cover about 4.5% of the United States' land area, an area larger than the state of California. About 52% of the wilderness area is in Alaska, with 57425569 acre of wilderness. They are located in 44 states (excepting Connecticut, Delaware, Iowa, Kansas, Maryland, and Rhode Island) and Puerto Rico.

The NPS has oversight of 43890500 acre of wilderness at 61 locations. The USFS oversees 36160078 acre of wilderness areas in 447 areas. The FWS has responsibility for 20702350 acre in 71 areas. BLM oversees 8726011 acre at 224 sites. Some wilderness areas are managed by multiple agencies.

Some areas are designated wilderness by state or tribal governments. These are not governed by the Federal National Wilderness Preservation System.

This table lists all U.S. areas that have been designated by the United States Congress under the Wilderness Act. The designation date is the date that the wilderness was signed into law. Some areas have been expanded or otherwise changed since their original designation.
