In the U.S. state of California, county routes are controlled and maintained by the respective counties in which they reside. However, they are generally patrolled by the state's California Highway Patrol.

County routes are designated with a letter (A, B, D, E, G, J, N, R, or S, depending on the region of the state, with several counties split between two region prefixes) followed by a number (example: G2). Therefore, the county routes are sorted alphabetically, from the northernmost region of California to the southernmost region. Routes with letters (A, B, D) are in the region of Northern California, letters (E, G, J) are in Central California, and (N, R, S) are in Southern California.

These routes are all part of the California Route Marker Program, which was established in 1958. This program was incorporated into the National Uniform County Route Marker Program created by the National Association of Counties in 1967. Not all counties choose to use the same marker; some have different systems of numbering their county routes.

List of California county routes[edit]

The county routes are alphabetically sorted by the prefix letter in its shield, followed by the corresponding number.
