List of National Historic Landmarks in California

This is a complete List of National Historic Landmarks in California. The United States National Historic Landmark (NHL) program is operated under the auspices of the National Park Service, and recognizes structures, districts, objects, and similar resources nationwide according to a list of criteria of national significance. The listings in the state of California express the diversity of California's heritage, including pre-Columbian peoples, the Spanish and Mexican periods, maritime activity, space exploration, and many other themes.

The table below lists all 148 sites, along with added detail and description. The sites are distributed across 36 of California's 58 counties.
