Your U.S. Representative for California's 12th congressional district is **Barbara Lee** (a Democrat). **A quick note on location:** Following the 2020 Census redistricting (which took effect in January 2023), CA-12 now covers parts of Alameda County in the East Bay, including **Oakland, Berkeley, San Leandro, Alameda, and Emeryville**. *(Note: Prior to 2023, the 12th district covered San Francisco and was represented by Nancy Pelosi, who is now the representative for the 11th district).* Because district lines can occasionally cut through neighborhoods or ZIP codes, you can verify this with 100% accuracy by entering your exact street address and ZIP code into the "Find Your Representative" tool at **[house.gov](https://www.house.gov/)**.
