2022–23 Boston Bruins season

The 2022–23 Boston Bruins season was the 99th season for the National Hockey League franchise that was established on November 1, 1924. In the offseason, the organization fired Bruce Cassidy, the team's head coach for the previous six seasons, and replaced him with Jim Montgomery. The season also saw the return of long-time Bruin David Krejci, who spent the previous season playing in the Czech Extraliga. The Bruins acquired players such as Pavel Zacha, via trade, and Tomas Nosek, via free agency, during the offseason, while also making trades for Dmitry Orlov, Garnet Hathaway, and Tyler Bertuzzi near the mid-season trade deadline to bolster their roster.

The Bruins finished the season as Atlantic Division winners, their third such title, and Presidents' Trophy winners for the fourth time in franchise history with a record-setting 135 points from 65 wins, 12 losses, and 5 overtime losses, with their 65 wins also serving as a new NHL record. The Bruins set many additional records during the season, including the most consecutive home wins to start the season (14), the fastest team to reach both 80 and 100 points,    and the fastest team to reach 50 wins. The Bruins also went 22 straight home games without a regulation loss to start the season before losing 3–0 to the Seattle Kraken.

Despite having an impressive regular season and securing home-ice advantage for the playoffs, the Bruins were upset in the first round by the Florida Panthers in seven games after surrendering a 3–1 lead. As such, they joined the 2007 New England Patriots, 2001 Seattle Mariners, 1906 Chicago Cubs, and 2015–16 Golden State Warriors as all-time winningest regular season teams not to win their respective league's championship. Unlike those teams, however, the Bruins lost in the first round of the playoffs, while the Mariners reached the ALCS and the Patriots, Cubs, and Warriors all reached their respective championship series or game. This season served as the last for Krejci and fellow long-time Bruin Patrice Bergeron as they would retire during the ensuing offseason.
