The Bald Hills are a range of mountains, in Humboldt County, California. The Bald Hills lie south of the Klamath and Trinity Rivers, between those rivers and Redwood Creek. The valleys at their feet and their lower slopes are covered by redwood forests but their summits are "bald", lacking woodland and instead are covered by meadows. These hills gave their name to the Bald Hills War fought between the local Indian tribes among these hills and the forces of local settler militia, California State Milita and California Volunteers and United States Army from 1858 to 1864.
