# California's 9th congressional district

38°00′N 121°18′W﻿ / ﻿38.0°N 121.3°W﻿ / 38.0; -121.3
California's 9th congressional district is a congressional district in the U.S. state of California. Josh Harder, a Democrat, has represented the district since January 2023.
Prior to redistricting by the California Citizens Redistricting Commission of 2011, the 9th district encompassed part of the East Bay region of the San Francisco Bay Area. Cities in the district included Oakland, Berkeley and Castro Valley. Most of that area became parts of 13th district, while the 9th district in 2012 through 2022 was primarily made up of portions of the 18th and 11th districts from the 2002 through 2012.
After the redistricting of 2011, the 9th district centered on Stockton. It consisted of most of San Joaquin County and portions of Contra Costa and Sacramento counties. Cities in the district include Galt, Oakley, Lodi, Mountain House, and Stockton.
With the redistricting in advance of 2022, the 9th district is still centered on Stockton, but Tracy, Manteca, and Ripon, which were formerly in California's 10th congressional district, are now part of this district, while Antioch, Lathrop and Brentwood are no longer in the district. Antioch and Brentwood are part of the new 10th district, which is now west of the 9th district (as opposed to south). Lathrop will be part of the new 13th district.
The district 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.
