The Marine Mammal Center is a nonprofit organization that rescues, rehabilitates and releases sick, injured and orphaned marine mammals.

Since 1975, the Center has cared for more than 16,500 animals that have been found along 600 miles of Northern and Central California coastline, from Mendocino County through San Luis Obispo County.

Since its humble beginnings over three decades ago, The Marine Mammal Center has grown into a world-class rescue and research Center, but its goals have remained unchanged: to rescue and humanely treat marine mammals in need; through scientific inquiry, increase our knowledge about marine mammals, their health and the health of the ocean; and through education, inspire ocean conservation and stewardship.

In June 2009, The Marine Mammal Center opened the doors of its newly re-built hospital and education facility. Visitors can view seal and sea lion patients from the observation deck; learn about marine mammals and the Center's work via exhibits; peer into different viewing windows to see feeds prepared, lab work, and even post mortems taking place, and take a stroll through the courtyard and gift store. Parking is limited and carpooling is recommended.

As a 501 (c)(3) non-profit organization, the Center relies on 80% of its funding from individuals and private donations.
