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 ninth largest national forest in the United States. The 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 one of the most visited "urban" forests 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 "foolish") 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.

On June 13, 2020, a wildfire ignited in the Tonto Basin area. The Bush Fire, as it was named, burned 193,455 acres (783 km2), becoming Arizona's fifth largest fire on record. The fire was sufficiently contained by July 1, prompting the Incident Management Team to transition control to the Forest Service, which subsequently conducted a Burned Area Emergency Response (BAER) assessment to begin rehabilitation efforts. Investigators determined the fire was human-caused.
