The 1970–71 Boston Bruins season was the Bruins' 47th season in the NHL. As defending champions, Boston set many NHL records. They earned 57 wins and 121 points, surpassing the previous records set by the 1968–69 Montreal Canadiens. They also scored 399 goals to shatter their own record set in 1968–69, and their goal differential of +192 surpassed the previous record set by the 1943–44 Montreal Canadiens as well. The NHL's top four scorers (Phil Esposito, Bobby Orr, Johnny Bucyk, and Ken Hodge), each with over 100 points, were all Bruins; previously, there had only been four players in the history of the NHL with 100-point seasons, and no other NHL franchise has ever produced the top four scorers in a season (the Bruins replicated the feat in 1973–74). With 76 goals and 152 points, Esposito broke Bobby Hull's single season record for goals, as well as his own single season points record, both set in 1968–69. Finally, with 102 assists, Orr broke the single season record for most assists that he set the previous year.

However, the team's unprecedented offence was shut down by rookie goaltender Ken Dryden, who guided the Montreal Canadiens to a seven-game upset against the Bruins in the first round of the playoffs.

All of the Bruins' aforementioned records have since been broken: The Montreal Canadiens earned 58 wins and 127 points in 1975–76. The Bruins reclaimed the record in 2023 with 65 wins and 135 points, beating the aforementioned Canadiens in 2022-23 Montreal earned a goal differential of +216 in 1976–77. Wayne Gretzky scored 109 assists and 164 points in 1980–81. Gretzky scored 92 goals while the Edmonton Oilers scored 417 total goals in 1981–82.

Offseason Bobby Orr signed the NHL's first one million dollar contract (to be paid out over five years).Numbelievable!, p.79, Michael X. Ferraro and John Venziano, Triumph Books, 2007, Chicago, Illinois,
