This is a list of state highways in the U.S. state of California that have existed since the 1964 renumbering. It includes routes that were defined by the California State Legislature but never built, as well as routes that have been entirely relinquished to local governments. It does not include the few routes that were relinquished before 1964 or the larger number of sign routes that were renumbered in or before 1964.

Each state highway in California is maintained by the California Department of Transportation (Caltrans) and is assigned a Route (officially State Highway Route[3][4]) number in the Streets and Highways Code (Sections 300-635). Under the code, the state assigns a unique Route X to each highway, and does not differentiate between state, US, or Interstate highways.

The new markers, like the old sign route shields, are in the shape of the spade used in the gold fields by California's 49er miners.

The marker or shield used for the State numbered route system is in the shape of an acorn, with the California Bear at the top and the words, 'State Highway' across the bottom of the shield.
