The Sonoma Mountains are a northwest-southeast trending mountain range of the Inner Coast Ranges in the California Coast Ranges System, located in Sonoma County, Northern California.
The Sonoma Mountains range is approximately fourteen miles (22.5 km) long. It separates the Sonoma Creek watershed from the Petaluma River and Tolay Creek watersheds. The highest point of this range is Sonoma Mountain, elevation 2,287 ft (697 m).
Jack London State Historic Park, Crane Creek Regional Park, and the Fairfield Osborn Preserve are both on Sonoma Mountain. A number of threatened and endangered species are found in the Sonoma Mountains including the fragrant fritillary (Fritillaria liliacea).
Many creeks rise in the Sonoma Mountains. From the northwestern slopes, Copeland Creek and Hinebaugh Creek flow to the Laguna de Santa Rosa, eventually entering the Pacific Ocean just south of Jenner, California. Matanzas Creek and Spring Creek flow north into Santa Rosa Creek, another tributary of the Laguna.
