Though long extirpated from the state, the grizzly bear remains the official state mammal of California.

This is a list of mammals in California, including both current and recently historical inhabitants.

The California Department of Fish and Wildlife (CDFW) monitors certain species and subspecies of special concern. These are mammals whose populations may be locally threatened, but which are excluded from federal and international conservation lists. Taxa of special concern in California are noted below, as are endemic, introduced, harvest, and vagrant species.

There are 226 mammal species listed, including 185 terrestrial and 42 marine.
