Mount Izaak Walton is a {{convert|12,077|ft|meter|adj=mid|-elevation|abbr=off|sp=us}} mountain summit located in the Sierra Nevada mountain range in Fresno County of northern California, United States. It is situated in the John Muir Wilderness, on land managed by Sierra National Forest. Mount Izaak Walton ranks as the 404th-highest summit in California. Topographic relief is significant as the northwest aspect rises {{convert|1,800|ft|m|abbr=off|sp=us}} above Izaak Walton Lake in approximately one mile. It is six miles northeast of Lake Thomas A Edison, and approximately {{convert|14|mi}} south-southeast of the community of Mammoth Lakes. The peak is set on Silver Divide, so precipitation runoff from the north side of this mountain drains into Fish Creek which is a tributary of the San Joaquin River, and from the south slope to Mono Creek, also a tributary of the San Joaquin.
