The San Francisco Mountains are a 20-mile-long (32 km) mountain range located in north‑central Beaver County, Utah, United States that extend into central-south Millard County.

Both ranges form the eastern border of the Wah Wah Valley Hardpan and the usually dry Sevier Lake which both have the same northeasterly trendline.

[2] The range is linear, with a high peaks section in the southwest; the northeast lower elevation foothills merge into the Cricket Mountains.

A smaller, almost circular mountain sub-range is attached on the southeast, the Beaver Lake Mountains, which is also adjacent to the town of Milford; the Beaver River flows north through Milford Valley and enters the desert region east of the mountain ranges.

Saint Francis of Assisi is the founder of the Franciscan Order of the Catholic Church and the patron saint of wildlife.
