Olustee Battlefield Historic State Park is a Florida State Park in the Osceola National Forest, near the town of Olustee. The site of Florida's largest Civil War battle, the park is located west of Jacksonville and east of Lake City, on U.S. 90. It also has the distinction of being the first park in the Florida State Park system. The State of Florida actually owns only of the Park, but manages another of the original battlefield under a Special Use Permit from the United States Forest Service.
