St. George Island State Park (also known as the Dr. Julian G. Bruce St. George Island State Park) is a Florida State Park located on the east end of St. George Island, approximately 10 miles southeast of Eastpoint, in northwestern Florida. Access to the park is off U.S. 98, by way of a 4 mile long bridge. The address is 1900 E. Gulf Beach Drive.

St. George is a barrier island, 28 miles (45 km) long and 2 miles (3 km) wide at its widest point. St. George Island is adjacent to Cape St. George Island. The island is separated from the mainland by a four-mile (6 km) long bridge across Apalachicola Bay, connecting to Eastpoint, Florida. Nearby towns include Eastpoint, Carrabelle and Apalachicola. St. George Island is informally divided into three regions: a State Park, a public strip of restaurants, bars, small businesses, homes and public beach, and a private and gated, highly exclusive housing community complete with its own airstrip. It is in this community that some of the most expensive multi-million dollar beach homes on the Gulf of Mexico are located.

The island is known for being quiet and tranquil due to its small size. Many occupants of the island rent out their homes during the spring and summer months. As of 2008, the island has no central sewage system and receives very little funding for road and infrastructure improvements, leading some to believe the island should form its own special taxing district. Saint George Island is said to be one of the most expensive islands on the Gulf to rent or own, and many purchase land on the island as an investment. A typical plot of land can range from $300,000.00 to $10,000,000.^{[citation needed]}

St. George Island State Park occupies the eastern nine miles (14 km) of the island. The park has a series of hiking trails, boardwalks and observation platforms. Bird watching is a popular activity there. The area is well known for its excellent variety of Apalachicola Bay and Gulf of Mexico fish and seafood including oysters, scallops, grouper, flounder, redfish, snapper, trout, mullet and others.
