NAPA. County seat, Napa. Created February 18, 1850. Named after Napa Valley. The word napa is of Indian derivation and has been variously translated as “grizzly bear,” “house,” “motherland” or “fish.” Of the many explanations of the names’s origin, the most plausible seems to be that it is derived from the Patwin word napo meaning house.
