The 1965 Stanley Cup Finals was the championship series of the National Hockey League's (NHL) 1964–65 season, and the culmination of the 1965 Stanley Cup playoffs. It was contested between the Chicago Black Hawks and the Montreal Canadiens. The Canadiens won the best-of-seven series, four games to three, to win the Stanley Cup. The seventh and final game of this series marked the first time that any NHL competition had taken place during the month of May, and at the time it was the latest finishing date for an NHL season.
