Sinopah Mountain (8,276 feet (2,523 m)) is located in the Lewis Range, Glacier National Park in the U.S. state of Montana. Sinopah Mountain rises prominently to the west of Two Medicine Lake. Sinopah means, ""kit fox" in Blackfeet, (who) was the Indian wife of Hugh Monroe (Rising Wolf) and daughter of Lone Walker, a powerful Blackfeet chief."

Like other mountains in Glacier National Park, the peak is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. 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.

Based on the Köppen climate classification, the peak is located in an alpine subarctic climate zone with long, cold, snowy winters, and cool to warm summers. Temperatures can drop below −10 °F with wind chill factors below −30 °F.
