Massive Mountain, Mountain summit in Alberta, Canada

Massive Mountain is a 2,435-metre summit in the Massive Range of Banff National Park, Alberta, rising 88 metres above its surroundings. It stands 2.9 km northeast of Mount Brett and 2 km southeast of Pilot Mountain, west of the Bow River valley. The mountain is built of sedimentary rock formed in shallow seas and pushed east during the Laramide orogeny.

Massive Mountain is built of sedimentary rock laid down from the Precambrian to the Jurassic in shallow seas. During the Laramide orogeny this rock was pushed east and over younger rock. It was named in 1918, either for its massive size or for a nearby siding of that name; the range's highest summit is Mount Brett at 2,984 m.

The name was assigned in 1918, and one account links it to a nearby railway siding also called Massive rather than to the mountain's size. The peak stands 2.9 km northeast of Mount Brett and 2 km southeast of Pilot Mountain, west of the Bow River valley.

Access is available via established routes that vary in difficulty and require proper climbing gear and weather awareness. Visitors should check local conditions and trail markings before starting their ascent.

Massive Mountain rises only 88 metres above its surrounding terrain, and its name has two explanations: it was named in 1918 for its massive size, or, according to another source, for a nearby railway siding of the same name. It lies 2.9 km northeast of Mount Brett and 2 km southeast of Pilot Mountain, west of the Bow River valley.
