Murrells Inlet is an unincorporated area and census-designated place straddling the line between Horry and Georgetown Counties in South Carolina, United States. The population was 7,547 at the 2010 census. The community was once primarily a fishing village, but has grown substantially in modern time, along with the rest of the Grand Strand, into a popular tourist and retirement location. It is most known for the Murrells Inlet Marshwalk, a ⁄2-mile-long boardwalk overlooking a salt marsh and which houses many restaurants.
