Bear Valley Hot Spring, Idaho is a backcountry geothermal spring in the Boise National Forest in Valley County, near the towns of Stanley and Lowman in central Idaho. The source water reaches 130 degrees Fahrenheit, with the main soaking pool resting at approximately 104 degrees.

Bear Valley Creek is a tributary of the Middle Fork of the Salmon River, flowing through dense forest and meadow in the mountains south of the Frank Church River of No Return Wilderness. The springs have been featured in Backpacker magazine and are considered by many visitors to be among the finest natural hot springs in Idaho for the combination of water quality, pool size, and mountain scenery. The area has active bear populations, as the name suggests.
The pools are primitive and visitor-maintained. Red spider mites have been reported in the area by some visitors. No facilities exist at the springs.
