Which team holds the record for most wins in a single season?

The Boston Bruins hold the NHL record for most wins in a single season, with 65.

Boston set the mark during the 2022–23 regular season, finishing 65–12–5 for 135 points. The Bruins also established league records for points and regulation wins that season, making their performance one of the strongest regular-season campaigns in NHL history.

The record is about regular-season victories, not playoff wins or total games won across a franchise's entire history. It is also easy to confuse this achievement with the Detroit Red Wings' 62-win 1995–96 season, which previously stood as the single-season wins record and remains one of the league's most famous regular seasons.

Despite their historic regular season, Boston's 2023 playoff run ended in the first round. The Bruins lost to the Florida Panthers in seven games after leading the series 3–1, an outcome often cited when discussing the difference between regular-season dominance and playoff success.
