Mount Indefatigable is a 2,667-metre (8,750-foot) mountain summit located in Peter Lougheed Provincial Park in the Canadian Rockies of Alberta, Canada. The peak is visible from Alberta Highway 40, and the Kananaskis Lakes area. Mount Indefatigable's nearest higher neighbor is Mount Invincible, 1.8 km (1.1 mi) to the northwest. Like so many of the mountains in Kananaskis Country, Mount Indefatigable received its name from the persons and ships involved in the 1916 Battle of Jutland, the only major sea battle of the First World War.
