Thunderbird Mountain (8,805 feet (2,684 m)) is located in the Livingston Range, Glacier National Park in the U.S. state of Montana.

Thunderbird Glacier is located immediately northeast of the mountain.

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.
