Mount Warren is a mountain summit located at the southeast end of Maligne Lake in Jasper National Park, in the Canadian Rockies of Alberta, Canada. Mount Warren is often seen in the background of iconic calendar photos of Spirit Island and Maligne Lake. The mountain rises in less than from the lake giving it dramatic local relief. Mount Warren is situated at the northwest edge of the Brazeau Icefield, and its nearest higher peak is Mount Brazeau, to the southeast. Monkhead is a lower secondary summit to the northwest of the true summit.
