Grizzly Creek Redwoods State Park is a state park of California, USA, harboring groves of coast redwoods in three separate units along the Van Duzen River. It is located 20 miles (32 km) east of Eureka, California, then another 18 miles (29 km) east of Fortuna on State Route 36. The small park was created by a donation from Owen R. Cheatham, founder of Georgia-Pacific Corporation, who wanted to preserve the stand of redwoods in perpetuity. Originally established in 1943, the park has grown to 430 acres (170 ha). The Cheatham Grove unit, 4 miles (6.4 km) west of the main unit, was added to the park in 1983 due to efforts of the Save-the-Redwoods League.
