Atlantic Beach is a town in Horry County, South Carolina, United States, part of the Grand Strand tourist region.

Atlantic Beach is commonly nicknamed "The Black Pearl"; the rich culture of the town of Atlantic Beach was formed of mostly Gullah people, descendants of slaves who lived for 300 years on the Sea Islands from Wilmington, North Carolina to Jacksonville, Florida.

In the early 1930s, defying Jim Crow laws in the segregated South, debunking black stereotypes, and broadening the enterprises of the Gullah people, black men and women opened hotels, restaurants, night clubs, and novelty shops in Atlantic Beach.

Visitors would travel along Interstate 95, US 17 and SC 9, coming from nearby southern states, where racial segregation took its toll.
