The Surfrider Foundation is a U.S. 501(c)(3) non-profit environmental organization that works to protect and preserve the world's oceans, waves and beaches.

Headquartered in San Clemente, California, the Surfrider Foundation maintains a small staff, which work to support the organization's network of 200+ grassroots volunteer-led chapters and student clubs.

The foundation was a key plaintiff in the battle to open Martin's Beach in San Mateo County, California.

On September 25, 2020, California governor Gavin Newsom signed AB1426 prohibiting the development of any roadway(s) that might impact or encroach upon the state beach, ending the decades long battle.
