2022 United States House of Representatives elections in California

The 2022 United States House of Representatives elections in California were held on November 8, 2022, to elect representatives for the 52 seats in California (reduced from 53 in the redistricting cycle following the 2020 United States census). This marked the first time in the state's history where it lost a seat.

This was the second election using congressional districts drawn by the California Citizens Redistricting Commission (after 2012 following the 2010 census). The commission submitted the final maps to the California Secretary of State on December 27, 2021. These new districts are considered "enacted" as of December 27, 2021. However, there was a 90-day period that ended on March 27, 2022, for any referendum petition to be filed to prevent the maps from becoming effective. Even after becoming effective, these newly redrawn districts did not become official until the 2022 primary and general elections, and the new districts will not actually exist until the 2023 inaugurations.

Of the fifty-three incumbents, six retired. All remaining incumbents were re-elected, and five new representatives were elected, two of which were from newly drawn districts.
