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.

The 13th district is located in the San Joaquin Valley, comprising all of Merced County; most of the population of Madera County; and parts of Stanislaus, Fresno, and San Joaquin counties. Cities in the district include Merced, Madera, Ceres, Patterson, Lathrop, Chowchilla, Atwater, Coalinga, and Mendota; as well as the southern parts of both Modesto and Turlock. The 13th is considered a swing district and was one of 13 congressional districts that voted for Donald Trump in the 2024 presidential election while simultaneously electing a Democrat in the 2024 House of Representatives elections.

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. This area is now covered by the 12th district.
