The 2020 United States House of Representatives elections in California were held on November 3, 2020, to elect the 53 U.S. representatives from the state of California, one from each of the state's 53 congressional districts. The elections coincided with the 2020 U.S. presidential election, as well as other elections to the United States House of Representatives, elections to the United States Senate, and various state and local elections.
This is the first general election since 1994 in which a Republican defeated an incumbent House Democrat in California. This year, despite the statewide dominance by Democratic presidential nominee Joe Biden, a record-breaking number of Republicans defeated Democratic House incumbents: Young Kim defeated Gil Cisneros in District 39, Michelle Park Steel defeated Harley Rouda in District 48, and David Valadao defeated TJ Cox in District 21 to reclaim his old seat. This happened even as Democrats won the statewide combined House vote by a wider margin than Biden. Mike Garcia also defeated Christy Smith in District 25 to retain the seat he flipped in the May 12 special election to fill the seat vacated by Katie Hill.
