The 1978 Stanley Cup Final was the championship series of the National Hockey League's (NHL) 1977–78 season, and the culmination of the 1978 Stanley Cup playoffs. It was contested between the Boston Bruins and the defending champion Montreal Canadiens, making their third straight appearance in the Finals. The series was a rematch of the 1977 Stanley Cup Final. The Canadiens won the best-of-seven series, four games to two, to win their third consecutive Stanley Cup championship and their 21st overall. This was the last time that both the Boston Bruins and Montreal Canadiens met in the Stanley Cup Final. The Canadiens eventually joined the Bruins in the Adams Division (now the Atlantic Division) in 1982, rendering a rematch impossible.
