Mahtotopa Mountain (8,677 feet (2,645 m)) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana.

Mahtotopa is an incorrect spelling of "Mato-tope" which comes from Lakota, Mato Topa, the Mandan chief known as Four Bears.

Based on the Köppen climate classification, Mahtotopa Mountain is located in a subarctic climate zone characterized by long, usually very cold winters, and short, cool to mild summers.

Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170 million years ago when the Lewis Overthrust fault pushed an enormous slab of precambrian rocks 3 mi (4.8 km) thick, 50 miles (80 km) wide and 160 miles (260 km) long over younger rock of the cretaceous period.
