I'll look up the current U.S. representative for California's 9th congressional district. Your U.S. representative for California's 9th Congressional District (CA-09) is **Josh Harder**, a Democrat. Josh Harder, a Democrat, has represented the district since January 2023. Currently, the district includes most of San Joaquin County and small parts of neighboring Contra Costa County and Stanislaus County. It includes the cities of Stockton, Lodi, Tracy, Manteca, and Mountain House in San Joaquin County, and the census-designated place of Discovery Bay in Contra Costa County. One thing worth noting: this Congressional district was established by the voters of California with the passage of Proposition 50 (2025) on November 4, 2025 and will go into effect after the November 2026 elections and upon seating of the 120th Congress, January 3, 2027. So the district boundaries will change in the future, but Josh Harder is your current representative. If you'd like, I can help you find his contact information or office locations.
