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.
This division features a number of classic and modern NHL rivalries, including Bruins–Canadiens, 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.
