The Bob Marshall Wilderness Area is a congressionally-designated wilderness area located in Western Montana region of the United States.

Formally designated in 1964, the Bob Marshall Wilderness extends for 60 miles (97 km) along the Continental Divide and consists of 1,009,356 acres (4,084.72 km2).
