This is a list of the longest winning streaks in National Hockey League (NHL) history. The list includes streaks that started at the end of one season and carried over into the following season. There are two lists, streaks that consist entirely of regular-season games and streaks made up of playoff games only. The Pittsburgh Penguins hold the record for the longest winning streak in NHL history at 17 games, which was set in the 1992–93 season; that team won the Presidents' Trophy for having the league's best record of 56–21–7. In the previous season, that team won a NHL-record total of 14 straight games in the playoffs. Only regular season winning streaks lasting twelve or more games are included.
The Montreal Canadiens appear six times across both lists, with four streaks over 11 games in the postseason and two streaks over 12 games or more in the regular season. The Boston Bruins appear four times across both lists, with three of those streaks over 10 games occurring in the regular season.
Prior to the 2005–06 season, tie games were abolished in favor of a shootout.
