Alice Lake is an alpine lake in the western United States in central Idaho, located high in the Sawtooth Mountains in the Sawtooth National Recreation Area.

In Blaine County, the lake is one of the largest in the Sawtooth Wilderness and is most easily accessed via the trailhead at Pettit Lake, accessed from State Highway 75 via Sawtooth National Forest road 208.

With a surface elevation of 8,602 feet (2,622 m) above sea level, Alice Lake can remain frozen into early summer.

The lake is framed by the rocky peaks of the Sawtooth Mountains, to the east is El Capitan at 9,901 feet (3,018 m).
