The Humboldt Redwoods State Park is a state park in Weott, California. It is the third largest park in the California State Park System with 53,000 acres of total area.

Established in 1921 by the Save-the-Redwoods League, the Humboldt Redwoods State Park was created to preserve the old-growth Redwoods in the area. The site is most famous for its coast redwoods. Most of the trees in the site are also redwoods, but there is also a small portion of Coast Douglas-fir. The park is also home to the fourth tallest measured living redwood, known as the Stratosphere Giant.

Aside from the excellent and gigantic trees, the Humboldt Redwoods State Park is also a site for camping, fishing, hiking, biking, horseback riding, and picnicking.
