California's 53rd congressional district was a congressional district in the U.S. state of California. It was last represented by Sara Jacobs, who succeeded Susan Davis following the 2020 election. It was eliminated following the 2020 United States redistricting cycle, becoming the first congressional seat to be lost after a census in California's history.
The district was in San Diego County before it was abolished. It included eastern portions of Chula Vista, western portions of El Cajon, central and eastern portions of the city of San Diego, as well as eastern suburbs such as Bonita, La Mesa, Lemon Grove, and Spring Valley in their entirety.
