The 2018 United States House of Representatives elections in California were held on November 6, 2018, with the primary elections being held on June 5, 2018. Voters elected 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 elections of other offices, including a gubernatorial election, other elections to the House of Representatives, elections to the United States Senate, and various state and local elections.

Democrats won in seven congressional districts previously represented by Republicans, all of which voted for Hillary Clinton in 2016. This reduced the California House Republican delegation by half and left the Republican Party with the fewest seats in California since just before the 1946 election cycle.

Republican incumbents Jeff Denham, David Valadao, Steve Knight, Mimi Walters, and Dana Rohrabacher (who had been elected to fifteen terms) were all defeated. Democrats also picked up two open seats previously held by retiring GOP incumbents: thirteen-term incumbent Ed Royce and nine-term incumbent Darrell Issa. The seven Democratic House pickups in California were the most made by the party in the 2018 election cycle.
