The 2014 California State Assembly elections were held on Tuesday, November 4, 2014, with the primary election held on June 3, 2014, coinciding with the elections of State Senate elections and other races, including the gubernatorial election.

Ultimately, the elections saw the California Republican Party pick up districts 16, 36, 65, 66, and recapture the vacant district 40, while losing district 44, thus rolling back the three-seat gain that the Democrats made in the 2012 elections, and ending their two-thirds supermajority in the chamber.
