Red Mountain is a 7,658 ft summit in the North Cascades Range of Washington, United States. It is located in Skagit County and within North Cascades National Park and the Stephen Mather Wilderness. It is situated on a smooth ridge of brick-red color at the western culmination of Ragged Ridge. Like many peaks of the North Cascades, Red Mountain is more notable for its large, steep rise above local terrain than for its absolute elevation. The nearest higher peak is Cosho Peak, to the east-southeast. Precipitation runoff from Red Mountain drains into the Skagit River via Panther and Fisher Creeks.
