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. Special elections are conducted in two rounds. The first round is an open primary. The second round is cancelled if one of the candidates receives more than 50% of the vote in the first round. Prior to 2012, the top vote getter from each party in the first round would advance to the second round. Since the passage of Proposition 14 in 2010, the top two vote getters in the first round, regardless of party, advance to the second round.
