The Atlantic Division is one of the three divisions in the Eastern Conference of the National Basketball Association (NBA). The division consists of five teams, the Boston Celtics, the Brooklyn Nets, the New York Knicks, the Philadelphia 76ers, and the Toronto Raptors. All teams, except the Raptors, are located on the East Coast of the United States. However, Toronto sports teams have over the years enjoyed rivalries with teams in the Northeastern United States (particularly, Toronto teams also share divisions with Boston and New York teams in Major League Baseball and the National Hockey League).
The division was created at the start of the 1970–71 season, when the league expanded from 14 to 17 teams with the addition of the Buffalo Braves, the Cleveland Cavaliers and the Portland Trail Blazers. The league realigned itself into two conferences, the Western Conference and the Eastern Conference, with two divisions in each conference. The Atlantic Division began with four inaugural members, the Celtics, the Braves, the Knicks and the 76ers.[1] The Celtics, the Knicks and the 76ers all joined from the Eastern Division.
The Celtics have won the most Atlantic Division titles with 25. Nine NBA champions have come from the Atlantic Division. The Celtics have won seventeen championships,[2] while the Knicks, the 76ers and the Raptors have won one championship each. All of them, except the 1972–73 Knicks, were division champions. In the 1983–84 season, all five teams from the division qualified for the playoffs. In the 1982–83 season, all teams in the division had winning percentages above 0.500 (50%).
Since the 2021–22 season, the Atlantic Division champion has received the Nat "Sweetwater" Clifton Trophy, named after Hall of Famer Nathaniel Clifton.[3]
