 A post-season appearance streak is continued by making the NHL playoffs in consecutive years after the regular season.Since the first round of the playoffs normally consists of 8 series, there will always be 16 teams in this list (of the 31 teams in the NHL), except for 2020 as the league expanded the playoffs to 24 teams due to the COVID-19 pandemic.This is a list of teams that have active post-season series win streaks.
