Mount Bullion (formerly Princeton and La Mineta) is a census-designated place (CDP) in Mariposa County, California, United States, along California State Route 49 in the Mother Lode country of the western Sierra Nevada. The community lies 5 miles (8 km) northwest of Mariposa, the county seat, at an elevation of 2,152 feet (656 m). The population was 154 at the 2020 United States census.

Mount Bullion developed as a Gold Rush-era mining settlement in the 1850s. Originally called La Mineta (Spanish for "little mine"), the community was later renamed Princeton for a nearby mine before receiving its present name in honor of U.S. Senator Thomas Hart Benton, whose nickname "Old Bullion" reflected his advocacy for hard currency policies.
