California's 13th congressional district is a congressional district in the U.S. state of California. Adam Gray, a Democrat, has represented this district since January 2025.

In the 2022 redistricting cycle, the district was moved to the San Joaquin Valley, while the old 13th district was renumbered as the 12th. The new 13th district includes all of Merced County; most of the population of Madera County; and parts of Stanislaus, Fresno, and San Joaquin counties. It includes the cities of Merced, Madera, Ceres, Patterson, Lathrop, Chowchilla, Atwater, Coalinga, and Mendota; as well as the southern parts of both Modesto and Turlock. The new 13th district is considered a Democratic-leaning swing district. Despite that, Duarte was narrowly elected to represent it in 2022. As a result, it was one of 18 districts won by Republicans in 2022 that voted for Joe Biden in the 2020 presidential election.

Prior to the 2022 redistricting, the 13th district contained cities in the northwestern portion of Alameda County including Alameda, Albany, Berkeley, Emeryville, Oakland, Piedmont, and San Leandro.
