Rock Peak is a 7,583-foot-elevation (2,311-meter) mountain summit in Sanders County, Montana.

Rock Peak is located 22 miles (35 km) south of Libby, Montana, in the Cabinet Mountains Wilderness, on land managed by Kaniksu National Forest.

[1] Precipitation runoff from the mountain's south slopes drains into Rock Creek, whereas the north slope drains into headwaters of East Fork Bull River, and both are tributaries of the Clark Fork River.

Topographic relief is significant as the summit rises 4,100 feet (1,200 m) above Rock Creek in 1.7 mile (2.7 km).

The mountain's toponym has been officially adopted by the U.S. Board on Geographic Names.
