Humphreys Peak (Hopi: Aaloosaktukwi, Navajo: Dookʼoʼoosłííd "its summit never melts"^[5]) is the highest mountain and the second most prominent peak after Mount Graham in the U.S. state of Arizona.^[6] With an elevation of 12,633 feet (3,851 m),^[1] it is located within the Kachina Peaks Wilderness in the Coconino National Forest, about 11 miles (17.7 km) north of Flagstaff, Arizona. Humphreys Peak is the highest of a group of dormant volcanic peaks known as the San Francisco Peaks.^[4]

Humphreys Peak was named in about 1870 for General Andrew A. Humphreys, a U.S. Army officer who was a Union general during the American Civil War, and who later became Chief of Engineers of the United States Army Corps of Engineers. However, a United States General Land Office map from 1903 showed the name San Francisco Peak applied to this feature (apparently borrowed from San Francisco Mountain on which the peak stands). Thus the United States Board on Geographic Names approved the variant name in 1911. In 1933, the application of the names was rectified.^[7]
