Longest active droughts.
Post-season appearance droughts.
A post-season appearance drought is continued by not making the NHL playoffs after the regular season. Since the first round of the playoffs consists of 8 series (16 teams) and there are 31 teams in the NHL, there will always be 15 teams that did not make the most recent playoffs on this list.
The other 16 teams – the Boston Bruins, Calgary Flames, Carolina Hurricanes, Colorado Avalanche, Columbus Blue Jackets, Dallas Stars, Nashville Predators, New York Islanders, Pittsburgh Penguins, San Jose Sharks, St. Louis Blues, Tampa Bay Lightning, Toronto Maple Leafs, Vegas Golden Knights, Washington Capitals and Winnipeg Jets – all qualified for the 2019 Stanley Cup playoffs. 
Post-season series win droughts.
A post-season series win drought is continued either by not making the playoffs in a season or by making the playoffs in a season but subsequently losing the first round series. Since the first round of the NHL playoffs consist of 8 series (16 teams), there will always be 23 teams in this list – the 15 teams that do not qualify for the post-season, plus the 8 teams that lose their first round series.
The other 8 teams – the Boston Bruins, Carolina Hurricanes, Colorado Avalanche, Columbus Blue Jackets, Dallas Stars, New York Islanders, San Jose Sharks and St. Louis Blues – all won a post-season series in the 2019 Stanley Cup playoffs.
