Hunting Island is a secluded semitropical barrier island located east of Beaufort, South Carolina, United States in between Harbor Island and Fripp Island. Since 1935, it has been classified as a state park. It is the most-visited state park facility in South Carolina and is a part of the ACE Basin estuarine reserve area. Known for its natural environment, the island remains one of the few remaining undeveloped Sea Islands in the Lowcountry. The park is known for its 19th century lighthouse which bears its name. The park's beach has been featured in several travel publications and was listed in 2013 as a Top 25 beach in the United States by TripAdvisor.

In the 1930s, the island was developed into a state park by the Civilian Conservation Corps as bridges were constructed to connect the outer Sea Islands with Beaufort. Thanks to limited human development, the island remains a preserve for its abundant wildlife. There are more than of beach, a dense maritime forest in the interior areas, and an extensive saltwater marsh on the western side. The most notable attraction is the 19th-century lighthouse, listed on the National Register of Historic Places. While not operational, the lighthouse tower features a rotating light in the tower that is turned on at night. The southern terminus of U.S. Route 21 has been on Hunting Island since 1953. US 21 extended to the south end of the island until about 1980, when erosion destroyed a portion of the highway, forcing the state to create a new entrance to the park and a set of one-lane roads through the palmetto forest. US 21 now ends at the point where it formerly veered east toward the lighthouse. Since 1980, Hunting Island has suffered major beach erosion as a result of heavy tides from the confluence of the Atlantic Ocean and Saint Helena Sound, and is expected to
