2024 United States House of Representatives elections in California

The 2024 United States House of Representatives elections in California will be held on November 5, 2024, to elect the 52 U.S. representatives from the State of California, one from all 52 of the state's congressional districts. The elections will coincide with the 2024 U.S. presidential election, as well as other elections to the House of Representatives, elections to the United States Senate, and various state and local elections.

Six incumbent representatives, Barbara Lee of the 12th district, Adam Schiff of the 30th district, Katie Porter of the 47th district, Anna Eshoo of the 16th district, Tony Cárdenas of the 29th district, and Grace Napolitano of the 31st district, have announced they will not seek re-election in 2024; Lee, Schiff, and Porter will instead run for U.S. Senate.

House Majority PAC, a super PAC affiliated with the Democratic Party, has announced that it will target four California Republicans in 2024: Mike Garcia of the 27th district, Young Kim of the 40th district, Ken Calvert of the 41st district, and Michelle Steel of the 45th district. Garcia, Kim, and Steel all represent districts that Joe Biden won in the 2020 presidential election, while Calvert's district narrowly voted for Donald Trump. There are two other California Republicans who represent Biden-won districts, John Duarte of the 13th district and David Valadao of the 22nd district.

Several California Republicans will receive assistance from Protect the House 2024, a joint fundraising committee launched by former U.S. Speaker of the House and California Republican Kevin McCarthy to support vulnerable House Republicans. Among the representatives included in the committee are Duarte, Valadao, Garcia, Calvert, and Steel, as well as Kevin Kiley of the 3rd district.

District 16
The incumbent is Democrat Anna Eshoo, who was re-elected with 57.8% of the vote in 2022 against another Democrat. She did not seek re-election. Former San Jose mayor Sam Liccardo advanced to the general election a week after the primary. His challenger will be state assemblyman Evan Low.

By April 3, both Low and Santa Clara County supervisor Joe Simitian tied with 30,249 votes each, and were expected to advance to the general election under a stipulation by California elections code regarding a second-place tie in primary elections. However, a recount was requested by two voters shortly thereafter. The recount request was controversial, with Low's campaign accusing Liccardo of being behind it. At the conclusion of the recount on May 1, Low ultimately edged out Simitian by a margin of 5 votes, with Low gaining 12 votes and Simitian 7.
