Hamburg State Park is a 741 acre (3.00 km<sup>2</sup>) state park located near Jewell and Warthen in the U.S. state of Georgia. It is home to a 1921 water-powered grist mill still operating today, and a museum with antique agricultural tools and appliances used in rural Georgia. The park's location on the 225 acre (0.91 km<sup>2</sup>) Hamburg Lake makes it a great place for fishing.
The state park took its name from the former industrial town of Hamburg, South Carolina.
