List of special elections to the California State Assembly

Special elections to the California State Assembly are called by the Governor of California when a vacancy arises within the State Assembly. Most special elections are conducted in two rounds. The first is an open primary and the candidate with the most votes must have a majority of the votes plus one to win the seat. If no candidate wins a majority a second round is held with the two top candidates regardless of party.

Recall elections, the process by which voters petition for the removal of an elected official, are also included.
