Beebe Mountain is a mountain summit located in the Cascade Range in the U.S. state of Washington. It is situated on the border of North Cascades National Park. Its nearest higher neighbor is Elija Ridge, to the southwest, and McKay Ridge is set to the northeast on the opposite side of the North Cascades Highway. The mountain's name honors Frank Beebe who worked for the Forest Service and maintained a cabin near the base of the mountain in the 1920s. Precipitation runoff on the mountain drains into Ross Lake via Granite Creek and Panther Creek.
