The Humboldt-Toiyabe National Forest (HTNF) is the principal U.S. National Forest in the U.S. state of Nevada, and has a smaller portion in Eastern California. With an area of 6,289,821 acres (25,454.00 km²), it is the largest National Forest of the United States outside of Alaska.

HTNF does not resemble most other National Forests in that it has numerous fairly large but non-contiguous sections scattered about most of the state of Nevada and a portion of eastern California. Its 10 ranger districts are scattered across the many mountain ranges in Nevada, from the Santa Rosa Range in the north to the Spring Mountains near Las Vegas in the south. A part of the forest (about 11%) is in eastern California, in the areas around Bridgeport and Markleeville, and other areas east of the Sierra Nevada.

The forest lies in 13 counties in Nevada and 6 in California. The counties with the largest amount of forest land are Nye, Elko, and White Pine in Nevada, and Mono County in California, but there are 15 other counties with land in this widely dispersed forest. Forest headquarters are located in Sparks, Nevada.

The smaller and more northeasterly Humboldt National Forest is located generally in eastern and northern Nevada, in parts of Elko, White Pine, Humboldt, Nye, and Lincoln counties. It has about 43.5% of the total area. There are local ranger district offices located in Ely, Elko, Wells, and Winnemucca.
