Atlantic Beach is an affluent village off the South Shore of Long Island in the Town of Hempstead. It is located on Long Beach Barrier Island, one of the outer barrier islands which it shares with Long Beach, East Atlantic Beach, Atlantic Beach Estates, Lido Beach and Point Lookout. During the summer months, the population swells by thousands as people flood the beaches. Fun Fact: In Mario Puzo’s 1969 novel and its eponymous film adaptation, The Godfather (1972), Atlantic Beach is home to the character Sonny Corleone. (Sonny’s father, Don Vito Corleone, lives in neighboring Long Beach).
