2024 United States Senate elections in California
The 2024 United States Senate elections in California will be held on November 5, 2024, to elect a member of the United States Senate to represent the state of California. There will be two ballot items for the same Class 1 seat: a special election to fill the seat for the final weeks of the 118th United States Congress (ending on January 3, 2025), and a general election for a full term that starts on January 3, 2025, starting in the 119th United States Congress. California uses a nonpartisan blanket primary, in which all candidates regardless of party affiliation appear on the same primary ballot and the two highest-placing candidates advance to the general election. Primary elections will take place on March 5, 2024. Democratic Senator Dianne Feinstein was first elected in a 1992 special election, defeating appointed Republican incumbent John Seymour to complete the term of Pete Wilson, who resigned to become California's governor. Feinstein won full terms in 1994, 2000, 2006, 2012, and 2018, and died in office on September 29, 2023, having already announced her retirement. Governor Gavin Newsom appointed Laphonza Butler as an interim replacement to hold office until the seat is filled in these elections.
