The Watchtower is a 2,791-metre (9,157 ft) mountain summit located in the Maligne River valley of Jasper National Park, in the Canadian Rockies of Alberta, Canada.

Its nearest higher peak is Sirdar Mountain, 11.64 km (7.23 mi) to the north.

[1] The Watchtower is composed of sedimentary rock laid down during the Cambrian period and pushed east and over the top of younger rock during the Laramide orogeny.

[6] Based on the Köppen climate classification, The Watchtower is located in a subarctic climate zone with long, cold, snowy winters, and mild summers.

Precipitation runoff from the mountain drains into Excelsior Creek and Watchtower Creek, both tributaries of the Maligne River which in turn empties into the Athabasca River.
