Del Norte Coast Redwoods State Park is a state park of California, United States, and a component of the Redwood National and State Parks. The property is about half old-growth forest of coast redwoods and includes 8 mi of wild Pacific coastline. The park was significantly expanded in 2002 with the 25000 acre Mill Creek Addition. Originally established in 1925, the park is now 31261 acre. The park was designated part of the California Coast Ranges International Biosphere Reserve in 1983.

Proposals for closure

A proposal to close a portion of this park placed it on the list of 48 California state parks proposed for closure in January 2008 by Governor Arnold Schwarzenegger as part of a deficit reduction program. The decision was rescinded following public outcry. However, in May 2011 the park was one of 70 state parks threatened with closure. In October 2011 the National Park Service agreed to provisionally take over management of Del Norte Coast Redwoods for one year.
