Stephen C. Foster State Park, Natural wildlife park in Fargo, Georgia, United States

Okefenokee State Park, formerly Stephen C. Foster State Park, is a 120-acre (49 ha) park in the Okefenokee Swamp, 18 miles northeast of Fargo in Charlton County, Georgia. It holds 64 tent, trailer and RV campsites, nine cottages, an interpretive center, three picnic shelters and a pioneer campground. The 1.5-mile Trembling Earth Nature Trail and 25 miles of day-use waterways give access to the cypress swamp and its alligators.

The land was established as part of the Okefenokee refuge system in the 1930s to protect one of North America's largest wetland areas. This early conservation effort recognized the ecological value of the swamp and laid the groundwork for modern preservation work in the region.

The park's name honoured Stephen Foster (1826–1864), the songwriter whose "Old Folks at Home" made Georgia's Suwannee River famous; in September 2026 the Georgia Department of Natural Resources renamed it Okefenokee State Park. The Suwannee River Visitor Center, 18 miles northeast of Fargo, holds exhibits on the swamp's animals, plants and ecosystem. Paddlers share the 25 miles of day-use waterways with alligators and wading birds.

Visitors can rent boats or join guided tours to explore the waterways and observe wildlife effectively. The site closes at dusk and weather conditions can change rapidly, so bringing waterproof clothing and insect repellent helps ensure a comfortable visit.

The preserve holds certification from the International Dark Sky Association for its minimal light pollution, making nighttime stargazing exceptionally clear. This designation is uncommon for protected lands and offers visitors a rare chance to see the night sky in remarkable detail.
