California's 11th senatorial district is one of 40 California State Senate districts. It is currently represented by Democrat Scott Wiener of San Francisco.
The district encompasses San Francisco and northern San Mateo County, including Daly City, Broadmoor, Colma, and parts of South San Francisco and San Bruno.
Due to redistricting, the 11th district has been moved around different parts of the state. The current iteration resulted from the 2021 redistricting by the California Citizens Redistricting Commission.
