The 1970 Stanley Cup Final 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 Final since 1958.

The Bruins swept the Blues to win their first Stanley Cup title since 1941. 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 Final again until 2019, where they also faced (and defeated) the Bruins in seven games, ending the second-longest Finals drought in league history.
