Guye Peak is a mountain in the northwest United States in the Cascade Range of Washington, east of Seattle. Named for Francis M. Guye, who held an iron mining claim on it in the 1880s, it lies in the Alpine Lakes Wilderness area and overlooks Snoqualmie Pass from the north. Guye Peak was first climbed on October 6, 1912, by Charles Hazlehurst, Hector Abel, Paul Dubuar, and Mary Hard. The climb is 2,000 feet (600 m) from the pass valley and has mixed rock climbing and scrambling, ranging from class 3 to class 5.6. It is popular partly because of easy access from Interstate 90.
