California’s 1st Congressional District is represented by James Gallagher (R) in the U.S. House of Representatives. The district is one of California’s seats in the 435-member House of Representatives.

California uses new district lines for the November 3, 2026 election (the map voters approved as Proposition 50), so this district’s boundaries change with that election. The redistricting tracker explains what changed.
