The Grand Strand is an arc of beach land on the Atlantic Ocean in South Carolina, United States, extending more than 60 miles (97 km) from Little River to Winyah Bay. It is located in Horry and Georgetown Counties on the NE South Carolina coast.

Winyah Bay is a coastal estuary that is the confluence of the Waccamaw River, the Pee Dee River, the Black River, and the Sampit River in Georgetown County, in eastern South Carolina. Its name comes from the Winyaw, who inhabited the region during the eighteenth century. The historic port city of Georgetown is located on the bay, and the bay generally serves as the terminating point for the Grand Strand.
