The 2012 United States House of Representatives elections in California were held on November 6, 2012, with a primary election on June 5, 2012. Voters elected the 53 U.S. representatives from the state, one from each of the state's 53 congressional districts. The elections coincided with the elections of other federal and state offices, including a quadrennial presidential election and a U.S. Senate election.
According to The Cook Political Report and Roll Call, the most competitive districts were the 7th, 10th, 26th, 36th, and 52nd; additionally, the 3rd, 9th, 24th, 41st, and 47th were rated as less than safe. Roll Call additionally listed the 21st district as competitive. Voters in 14 districts elected new representatives: the 1st, 2nd, 7th, 8th, 15th, 21st, 26th, 29th, 35th, 36th, 41st, 47th, 51st, and 52nd. Two districts, the 30th and the 44th, had two incumbents running against each other.
This was the first election using congressional districts drawn by the California Citizens Redistricting Commission. The districts, based on the 2010 United States census, were approved on August 15, 2011. It was also the first non-special election to use the nonpartisan blanket primary system established by Proposition 14. As a result, eight districts featured general elections with two candidates of the same party: the 15th, 30th, 35th, 40th, 43rd, and 44th with two Democrats; and the 8th and 31st with two Republicans.
