# California's 19th congressional district

California's 19th congressional district is a congressional district in the U.S. state of California, currently represented by Democrat Jimmy Panetta.
Following redistricting in 2021, the district includes most of Santa Cruz County and parts of Santa Clara County, Monterey County and San Luis Obispo County. The new 19th district includes the south side of San Jose and the entire cities of Santa Cruz, Monterey, Seaside, Paso Robles, and Atascadero. Most of the area was previously part of the 20th district, which moved to the Central Valley.
For much of the 20th century prior to the early 1990s, the district had encompassed areas to the south and much of Los Angeles County, California. Gradually it was redefined to take in central and northern counties instead.
