The South Central Rockies forests is a temperate coniferous forest ecoregion of the United States located mainly in Wyoming, Idaho, and Montana. It has a considerably drier climate than the North Central Rockies forest.

This ecoregion is located mainly in western Wyoming, but also in eastern and central Idaho, central Montana, northeastern Wyoming and southwestern South Dakota. It is centered on the Yellowstone Plateau, extending outward on connected mountain ranges, but the ecoregion also includes the isolated Bighorn Mountains and Black Hills, as well as smaller isolated ranges in central Montana. The area has a dry continental climate, with brief summers and long, cold winters.

The ecoregion is predominantly coniferous forest, dominated by lodgepole pine (Pinus contorta latifolia) due to relatively recent major fires in the area. Other trees include Engelmann spruce (Picea engelmanni), Rocky Mountain Douglas-fir (Pseudotsuga menziesii glauca), subalpine fir (Abies lasiocarpa) and trembling aspen (Populus tremuloides). Whitebark pine (Pinus albicaulis) is an important species at the upper tree line/krummholz zone. This ecoregion also contains mountain meadows, foothills grasslands, riparian woodlands, and alpine tundra. In some areas, geothermal activity creates distinct, warm habitats with unique floral communities.
