Who We Are

Welcome to the North Peninsula Chapter of the American Civil Liberties Union of Northern California.

Founded in 1979, our chapter is a cohort of dedicated volunteers who seek to protect and advance the civil liberties of all residents, employees, and students in San Mateo County. Recent chapter projects include work in criminal justice, voting rights, immigrants' rights, and the impact of technology on the right to privacy.

We are a chapter of the ACLU of Northern California, which is one of 54 branches that form the national ACLU organization. The ACLU is a nonprofit, nonpartisan organization guided by the principles of justice, fairness, equality, and freedom set forth in the Constitution.

The North Peninsula chapter serves the following cities in San Mateo County: Belmont, Brisbane, Broadmoor, Burlingame, Colma, Daly City, Foster City, Half Moon Bay, Hillsborough, Millbrae, Pacifica, San Bruno, San Carlos, San Mateo, and South San Francisco. (Other cities in San Mateo County are served by the Mid-Peninsula chapter.)

We generally meet on the third Wednesday of every month from 7:30-9:00 pm in San Mateo. During the COVID-19 pandemic, we meet by conference call and videoconference.

Our chapter does not discuss legal cases at our meetings. We do not offer legal services. The ACLU of Northern California has a civil liberties hotline at (415) 621-2488 or you may submit information electronically here.
