First establishment of California counties
On January 4, 1850, the California constitutional committee recommended the formation of 18 counties. They were Benicia, Butte, Fremont, Los Angeles, Mariposa, Monterey, Mount Diablo, Oro, Redding, Sacramento, San Diego, San Francisco, San Joaquin, San Jose, San Luis Obispo, Santa Barbara, Sonoma, and Sutter. On April 22, the counties of Branciforte, Calaveras, Coloma, Colusi, Marin, Mendocino, Napa, Trinity, and Yuba were added. Benicia was renamed Solano, Coloma to El Dorado, Fremont to Yola, Mt. Diablo to Contra Costa, San Jose to Santa Clara, Oro to Tuolumne, and Redding to Shasta. One of the first state legislative acts regarding counties was to rename Branciforte County to Santa Cruz, Colusi to Colusa, and Yola to Yolo.
The last Californian county to have been established is Imperial County, California in 1907.
List of California counties
The present number of counties was achieved over time by subdivision of many of the larger counties into smaller ones. The 1850 counties are marked with an asterisk (*).

Counties which no longer exist
- Klamath County was created in 1851 from the northern half of Trinity County, but in 1874 it was divided between Humboldt and Siskiyou counties.
- Pautah County was created in 1852 out of territory which, the state of California assumed, was to be ceded to it by the United States Congress from territory in what is now the state of Nevada. When the cession never occurred, the state legislature officially abolished the never-created county in 1859.
