Mount Hayden is an {{convert|8,362|ft|adj=on}}-elevation summit located in the Grand Canyon, in Coconino County of Arizona, United States. It is situated {{convert|1/2|mi|spell=in}} southeast of the Point Imperial viewpoint (eastern Walhalla Plateau), on the canyon's North Rim, where it towers {{convert|5,000|ft}} above the bottom of Nankoweap Canyon. Mount Hayden, also known as Hayden Peak, is named for Charles T. Hayden (1825–1900), an Arizona pioneer influential in the development of the Arizona Territory where he was known as the "Father of Tempe", and he established Arizona State University. He was also the father of US Senator Carl Hayden, as well as a probate judge. This geographical feature's name was officially adopted in 1932 by the U.S. Board on Geographic Names.

The first ascent of the summit was made in May 1978 by Joe Sharber, George Bain, and Abra Watkins via the north side ({{YDS|5.9}} A2).Todd R.
