The 1977 Stanley Cup Finals was the championship series of the National Hockey League's (NHL) 1976–77 season, and the finish to the 1977 Stanley Cup playoffs. It was played between the Boston Bruins and the defending champion Montreal Canadiens. The Bruins were making their first appearance in the final series since their loss in the 1974 Final. The Canadiens would win the best-of-seven series four games to none, to win their second straight Stanley Cup championship, and 20th overall.

Montreal defeated the St. Louis Blues 4–0 and the New York Islanders 4–2 to advance to the final.

Boston defeated the Los Angeles Kings 4–2 and the Philadelphia Flyers 4–0 to make it to the final.

Jacques Lemaire scored three game-winning goals, including the Cup-winner in overtime. Guy Lafleur won the Conn Smythe Trophy for scoring 10 goals and 17 assists during the playoffs.

• † Serge Savard served as interim captain when Yvan Cournoyer missed the whole playoffs due to a back injury.
• Bob Gainey was misspelled on the Stanley Cup as ROBERT GAINY, missing an "E". When the Replica Cup was created in 1992–93, ROBERT GAINEY was spelled correctly with 1977 Montreal.
• #3 Brian Engblom played two playoff games, no regular-season games and no games in the finals. His name was left off the Cup because he did not qualify. Engblom also won the Calder Cup with Mike Polich, and Pierre Mondou in 1977.
