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.

Campaign

In February, the California Democratic Party endorsed Jessica Morse. Calderon was able to successfully collect 322 CDP-credentialed delegate signatures needed to block the endorsement, in which Morse only received 44 delegate votes. However, CDP staff refused to accept the forms after it was alleged they closed doors early to prevent the submission. A petition was later filed with the Compliance Review Commission by Calderon. The CRC voted to accept and count the signatures, ultimately disqualifying enough signatures to proceed with Morse's endorsement.

California allows candidates to include their professional description under their names on the ballot, however Regina Bateson later challenged Morse's ballot designation title of "National Security Fellow" at the Sacramento Superior Court after months of controversy that Morse, who had not worked in three years, was "fluffing" her credentials. California's Secretary of State, Alex Padilla, had struck down Morse's 3 ballot designations before Judge Gevercer ruled that she presented "no credible evidence" to use the ballot designation of "National Security Fellow". Instead, he held that this title would mislead the average person about her recent activities. In the official Certified Candidate List, Morse's ballot designation was left blank.

Campaign

As a minority, millennial female running against an established male politician, Heng received a number of comparisons to Alexandria Ocasio-Cortez. Heng gained notoriety during the campaign for aggressive attack ads, including one where she depicted a silver-haired man who resembled Costa walking on a sidewalk in red high heels, which prompted questions of sexism. More controversially her campaign ran an ad featuring images of the Cambodian genocide, part of her family heritage. This ad was banned on Facebook and Twitter, leading to conservative claims of social media bias and unjustified censorship. Both social media sites ended up reversing course and allowed the commercials.
