The South San Juan Wilderness is a U.S. Wilderness Area located in the San Juan National Forest, east of Pagosa Springs, in southern Colorado. The area, which spans 158,790 acres, was designated a Wilderness Area and put into the National Wilderness Preservation System in 1980 by the United States Congress.

The Conejos, San Juan, and Blanco rivers all begin in the area.

The last known grizzly bear in Colorado was killed in the wilderness in 1979. Some believe that it is still home to a few grizzlies, but there is no sufficient evidence yet to prove this.
