The 2018 California State Senate elections were held on Tuesday, November 6, 2018, with the primary election being held on June 5, 2018. Voters in the 20 even-numbered districts of the California State Senate elected their representatives. The elections coincided with the elections of other offices, including for governor and the California State Assembly.
The Democratic Party gained three seats: the 12th, 14th, and 34th districts. These victories provided the Democrats with 29 seats and restored the two-thirds supermajority that they lost after the recall of Democratic state senator Josh Newman in June 2018.
