Pawleys Island is a town in Georgetown County, South Carolina, United States, and the Atlantic coast barrier island on which the town sits. The population was 138 at the 2000 census. The post office address also includes an unincorporated area on the mainland adjacent to the island, which includes a commercial district along the Ocean Highway (US Route 17) and a residential area between the highway and the Waccamaw River. The island is on the southern end of The Grand Strand and is one of the oldest resort areas of the US East Coast. The town of Pawleys Island, though, is only on the island. The island lies off the Waccamaw Neck, a long, narrow peninsula between the ocean and the river. The island is connected to the mainland by two bridges, the North Causeway and the South Causeway. At the southern tip of the island is a public beach access area.
