Mount Pétain is located on the border of Alberta and British Columbia on the Continental Divide. It was named in 1918 after Marshal Philippe Pétain.
The snow capped mountain can be reached from Height of the Rockies Provincial Park and Elk Lakes Provincial Park within British Columbia or Peter Lougheed Provincial Park in Alberta.
Beside the mountain several other geographical points are named for Pétain. Pétain Glacier is found next to Mount Joffre and Mount Pétain forming the Pétain Basin, with melt cascading down Pétain Creek Falls into the Pétain Creek below.
