Atlantic Beach Bikefest, officially the Memorial Day Black Pearl Cultural Heritage and Bike Festival, is held every Memorial Day weekend in the Town of Atlantic Beach, South Carolina. The Carolina Knight Riders started the festival in 1980 with the Atlantic Beach community, and it has grown to more than 250,000 visitors across the Grand Strand, one of the largest motorcycle rallies in the country.

The weekend brings meet and greets, parades, concerts, parties, street festivals and live entertainment. 2027 dates follow Memorial Day weekend and will be confirmed when the Town posts them.
