2015 Stanley Cup Playoffs

The 2015 Stanley Cup Playoffs of the National Hockey League (NHL) began on April 15, 2015, and ended on June 15, 2015 with the Chicago Blackhawks defeating the Tampa Bay Lightning four games to two in the 2015 Stanley Cup Finals.

The New York Rangers made the playoffs as the Presidents' Trophy winners with the most points (i.e. best record) during the regular season. They also came back from a 3–1 series deficit for the second consecutive year.

The Detroit Red Wings increased their consecutive post-season appearance streak to 24 seasons, the longest current streak and tied for the fourth-longest streak in NHL history.

The Winnipeg Jets qualified for the playoffs for the first time since the former Atlanta Thrashers franchise relocated to Winnipeg in 2011; the only time that the Thrashers/Jets franchise made the post-season was in 2007 and the last time that the city of Winnipeg hosted a playoff game was in 1996, the season before the previous Winnipeg Jets team relocated to Phoenix, Arizona, to become the Coyotes.

The Ottawa Senators became the first team in the NHL's modern era (since 1943–44) to overcome a 14-point deficit in the standings to clinch a playoff spot.

Also, the Calgary Flames returned to the playoffs after a six-year absence.

In total, five Canadian NHL teams qualified for the post-season, the most since 2004.

The Los Angeles Kings became the first defending Stanley Cup champions since the Carolina Hurricanes in 2007 to fail to make the playoffs.

The Boston Bruins failed to make the playoffs for the first time since 2007 and became the first reigning Presidents' Trophy winners to miss the post-season since the Buffalo Sabres in 2008 (and the third overall).

In addition, the San Jose Sharks failed to make the post-season for the first time since 2003, ending the NHL's second-longest active playoff streak.

For the first time since 2000, both the Eastern and Western Conference Finals went the full seven games.

The Tampa Bay Lightning became the first team in league history to face an Original Six team in four consecutive rounds of the playoffs in the same year, as they played against the Detroit Red Wings, Montreal Canadiens, New York Rangers and Chicago Blackhawks, respectively. They also became the fourth team to defeat three consecutive Original Six teams.
