The 1970 Stanley Cup Finals was the championship series of the National Hockey League's (NHL) 1969–70 season, and the culmination of the 1970 Stanley Cup playoffs. It was a contest between the Boston Bruins and the St. Louis Blues, who appeared in their third consecutive finals series. The Bruins were making their first appearance in the Stanley Cup Finals since . The Bruins won the series, four games to none. It was Boston's first Stanley Cup victory in 29 years. Bobby Orr scored the Cup-winning goal on Mother's Day against St. Louis' veteran Hall of Fame goalie Glenn Hall, with an assist from close friend and teammate "The Turk" Derek Sanderson, at forty seconds of overtime. The subsequent image of Orr flying through the air, his arms stretched out in victory — (he had been tripped by Blues' defenseman Noel Picard immediately after scoring the goal) — is considered the most famous and recognized hockey image of all time. With the win, the Bruins became the first American team to win the Stanley Cup since the Chicago Black Hawks in . The Blues, who had gone to the Finals their first three years in the league, would eventually lose each of the three series in four-game sweeps. St. Louis would not appear in a Stanley Cup Finals again until 2019, where they also faced the Bruins, ending the second-longest Finals drought in league history. Paths to the Finals Boston defeated the New York Rangers 4–2 and the Chicago Black Hawks 4–0 to advance to the Finals.
