California's 14th congressional district is a congressional district in the U.S. state of California. The district is currently vacant following the resignation of Eric Swalwell, a Democrat, who had represented the district since January 2013. In August 2026, Aisha Wahab was elected to replace Swalwell for the remainder of the 119th Congress. Wahab has not been sworn in, and the seat will remain vacant until she is.
As of the 2022 United States House of Representatives elections, the 14th district is in Alameda County and includes the cities of Hayward, Pleasanton, Livermore, Union City, Castro Valley, and parts of Dublin and Fremont. Immediately prior to that, the district included most of San Mateo County and the southwest side of San Francisco.
