Wasatch–Cache National Forest is a United States National Forest located primarily in northern Utah (81.23%), with smaller parts extending into southeastern Idaho (16.42%) and southwestern Wyoming (2.35%). The name is derived from the Ute word Wasatch for a low place in high mountains, and the French word Cache meaning to hide. The term cache originally referred to fur trappers, the first Europeans to visit the land. The Wasatch–Cache National Forest boundaries include 1,607,177 acres (6,504.01 km) of land.

Wasatch–Cache was headquartered in downtown Salt Lake City, Utah until August 2007 when its management was combined with the Uinta National Forest and is currently being managed as the Uinta–Wasatch–Cache National Forest. The merged forest is based out of South Jordan, Utah. The Kamas Ranger District was merged with the Uinta National Forest's Heber Ranger District in Heber City. With the newly included Uinta National Forest, the forest will expand to 2,487,896 acres (10,068.16 km).

In descending order of land area it is located in parts of Cache, Bear Lake, Franklin, Weber, Rich, Box Elder, Caribou, and Morgan counties. (Bear Lake, Franklin, and Caribou counties are in Idaho, and all the rest in Utah.) There are local ranger district offices located in Logan and Ogden.

The Wasatch National Forest portion is located in northeastern Utah and southwestern Wyoming. It has a land area of 905,724 acres (1,415.2 sq mi, or 3,365.3 km).
