Atlantic Division (NHL)

The Atlantic Division is a name used by the National Hockey League to describe a division of teams in the Eastern Conference.
The original Atlantic Division, the predecessor of which was the Patrick Division, was formed in 1993 as part of the Eastern Conference in a league realignment.
As part of a 2013 realignment, the entirety of the former Atlantic Division was realigned into the Metropolitan Division. The Atlantic Division name was assigned to a new division comprising the former Northeast Division plus the Florida Panthers and the Tampa Bay Lightning from the now-defunct Southeast Division, and the Detroit Red Wings, who moved from the Central Division of the Western Conference.
This division features a number of classic and modern NHL rivalries, including Bruins–Canadiens, Bruins–Maple Leafs, Canadiens–Maple Leafs, Maple Leafs–Red Wings, Maple Leafs–Senators, and Lightning–Panthers. Games between the division's three Canadian teams, plus the Bruins and Red Wings, are frequently featured on Hockey Night in Canada as its main attraction.
