The Bobby Brown State Park is a state park and recreation area in Elberton, Georgia. It preserves and maintains the site where the former town of Petersburg was located.

Named after Robert T. Brown, a former US Navy lieutenant who got killed during the Second World War, the Bobby Brown State Park covers 665 acres of what was the 1790s town of Petersburg. The town died because it was covered by water, mostly because it became where the Savannah and Broad Rivers met. When the water is low at the park, visitors can still see the foundations of the old structures of the town.

Visitors of the Bobby Brown State Park can also enjoy fishing, boating, picnicking, and hiking at the park.
