The 2024 California State Senate election took place on Tuesday, November 5, 2024, with the primary election being held on March 5, 2024. Voters in the 20 odd-numbered districts of the California State Senate will elect their representatives. The elections coincided with the elections for other offices, including the state Assembly.
There were 16 Democratic-held senate seats up for election in 2024, 3 Republican-held seats, and 1 open seat with no incumbent. Two Democratic incumbents, Dave Min and Josh Newman, were drawn into the same district during redistricting. In August 2024, Republicans gained one seat due to senator Marie Alvarado-Gil switching parties, increasing the size of their caucus to nine.
Republicans flipped one seat in the general election, doing so for the first time in a presidential election year since 1980.
