List of United States Senate elections in California

United States Senate elections in California occur every two years to elect individuals to represent the state in the Senate. Each state is allotted two senators elected to staggered six-year terms, with one-third of the Senate seats up for election each cycle. Initially, senators were selected by the state legislature under the U.S. Constitution, but since 1913, when the Seventeenth Amendment was ratified, they have been directly elected by voters.

California was admitted to the Union in 1850 with one seat designated as Class 1 and another as Class 3. Regular elections for these seats occur every two years, alternating between the classes. The next election for the Class 1 seat is scheduled for 2030, while the Class 3 seat will hold its next election in 2028. Special elections may also be held to fill mid-term vacancies.
