Mount Harrington is an 11,009-foot-elevation (3,356 meter) mountain summit located in Fresno County of northern California, United States.

[3] It is situated on Monarch Divide which is west of the crest of the Sierra Nevada mountain range, in the Monarch Wilderness, on the shared boundary of Sequoia National Forest with Sierra National Forest.

The first ascent of the summit was made July 27, 1951, by David Hammack and Anton Nelson.

[5] Most weather fronts originate in the Pacific Ocean, and travel east toward the Sierra Nevada mountains.

As fronts approach, they are forced upward by the peaks, causing them to drop their moisture in the form of rain or snowfall onto the range (orographic lift).
