The 1980 Stanley Cup Finals was contested by the New York Islanders in their first-ever Finals appearance and the Philadelphia Flyers, in their fourth Finals appearance, first since 1976. The Islanders would win the best-of-seven series four games to two, to win their first Stanley Cup and the third for a post-1967 expansion team after Philadelphia's Cup wins in 1974 and 1975.

Until 1995, this would be the last Finals series played entirely within one time zone.

New York defeated the Los Angeles Kings 3–1, the Boston Bruins 4–1 and the Buffalo Sabres 4–2 to advance to the Final.

Philadelphia defeated the Edmonton Oilers 3–0, the New York Rangers 4–1 and the Minnesota North Stars 4–1 to make it to the Final.

In game one, Denis Potvin scored the first power-play overtime goal in Stanley Cup Final history. In game six, Bob Nystrom scored the Cup winner in overtime, his fourth career overtime goal, at the time putting him alone behind Maurice Richard's six on the all-time overtime goal-scoring list. Ken Morrow joined the team after winning the Olympic gold medal and added the Stanley Cup to cap a remarkable season.

In the United States, the first five games were syndicated by the Hughes Television Network. Hughes used CBC's Hockey Night in Canada feeds for the American coverage. game six was televised in the United States by the CBS network, as a special edition of its CBS Sports Spectacular anthology series. This would be the last NHL game to air on U.S. network television until 1990, when the All-Star Game was televised on NBC. As of 2015, it is also the last Stanley Cup Finals game to be played in the afternoon (earlier than 5:00 local time).
