Mount Hoffmann, Mountain summit in Mariposa County, United States.

Mount Hoffmann is a summit in Mariposa County within Yosemite National Park in California. The peak displays prominent granite cliffs and rocky formations that characterize its slopes.

The mountain was named for Charles F. Hoffmann, a cartographer with the California Geological Survey who explored the Sierra Nevada in the mid-1800s. Its recorded ascent by John Muir in 1869 established the peak as a landmark in California mountaineering history.
