The 1979 Stanley Cup Final NHL championship series was contested by the New York Rangers and the defending champion Montreal Canadiens, making their fourth straight appearance. It was New York's first appearance since 1972. The Canadiens would win the best-of-seven series four games to one, to win their fourth consecutive Stanley Cup.

This was the last Stanley Cup Final until 2013 where both teams were from the Original Six, and the first of six consecutive Finals involving a team from the New York metropolitan area. The next five Finals would be contested by the Rangers' crosstown rivals the New York Islanders, who would win the first four of those series to forge a dynasty matching that of the Canadiens. By defeating the Rangers, the Canadiens completed the rare accomplishment of winning four consecutive titles in a North American league competition consisting of at least sixteen teams, a feat that had been achieved only twice before (both times by the New York Yankees) and has been achieved only once since (by the aforementioned Islanders).

Montreal defeated the Toronto Maple Leafs 4–0 and the Boston Bruins 4–3 (highlighted by the "too many men on the ice" game 7 overtime win) to advance to the finals.

New York defeated the Los Angeles Kings 2–0, the Philadelphia Flyers 4–1 and the New York Islanders 4–2 to make it to the finals.

The Canadiens won the Cup in five games, winning it on home ice for the first time since 1968. After the game Jacques Lemaire, Yvan Cournoyer and Ken Dryden retired, while head coach Scotty Bowman would leave the Canadiens to join the Buffalo Sabres, which would mark the end of the Canadiens' dynasty.
