The Tonto National Forest, encompassing 2,873,200 acres (1,162,700 ha; 11,627 km2), is the largest of the six national forests in Arizona and is the fifth largest national forest in the United States.  The Tonto National Forest has diverse scenery, with elevations ranging from 1,400 feet (427 m) in the Sonoran Desert to 7,400 feet (2,256 m) in the ponderosa pine forests of the Mogollon Rim (pronounced MOH-gee-on, or MUH-gee-own). The Tonto National Forest is also the most visited "urban" forest in the United States.  The boundaries of the Tonto National Forest are the Phoenix metropolitan area to the south, the Mogollon Rim to the north and the San Carlos and Fort Apache Indian Reservation to the east. The Tonto ( Spanish for "fool") is managed by the USDA Forest Service and its headquarters are in Phoenix. There are local ranger district offices in Globe, Mesa, Payson, Roosevelt, Scottsdale, and Young. 
Many wildlife species inhabit the forest including raccoons, bald eagles, black bears, coyotes, skunks, bobcats, roadrunners, prairie falcons, white-tailed deer, long-eared owls, mule deer, red-tailed hawks, Great blue herons, cougars, barn owls, ring-tailed cats, kestrels, pronghorns, javelinas, and elk.

The Tonto Forest Reserve was established on October 3, 1905 by the General Land Office. In 1906 the forest reserves were transferred to the U.S. Forest Service, and on March 4, 1907 Tonto became a National Forest. On January 13, 1908 the Pinal Mountains National Forest was added along with other lands. On July 1, 1908 part of Black Mesa National Forest and other lands were added, and on July 1, 1953 part of Crook National Forest was added. 
A land swap proposed as a part of the 2015 National Defense Authorization Act would permit a subsidiary of the Rio Tinto mining conglomerate, Resolution Copper Co., to acquire 2,400 acres of the Tonto National Forest, considered sacred for the San Carlos Apache Tribe, for purposes of copper mining. This proposal, in Section 3003, titled "Southeast Arizona Land Exchange", is strongly opposed by many Native Americans, including the 57 member tribes of The Affiliated Tribes of Northwest Indians, and by the Great Plains Tribal Chairmen’s Association.
