The Fitzsimmons Range is a small mountain range on the northwestern edge of the Garibaldi Ranges in southwestern British Columbia, Canada, located between the valleys of Cheakamus Lake (SW) and Fitzsimmons Creek (NE).

Most of the range is within Garibaldi Provincial Park, while its northeastern extremity is part of the resort municipality, and of the lands associated with the ski resort operation.

Beyond them is Singing Pass and Mount Fitzsimmons 2603 m (8540 ft) which is at the opposite end of the range from Whistler Mountain and the location of Fitzsimmons Glacier, which is the source of Fitzsimmons Creek.

Mount Fitzsimmons is part of the Overlord Massif, which is named for the highest peak in the range, Overlord Mountain, 2625 m (8612 ft), just to its west.
