The 2007 Stanley Cup playoffs of the National Hockey League began on April 11, 2007. The sixteen teams that qualified, eight from each conference, played best-of-seven series for conference quarterfinals, semifinals and championships, and then the conference champions played a best-of-seven series for the Stanley Cup. The series ended on June 6 with the Anaheim Ducks defeating the Ottawa Senators in five games to win their first ever championship.
For the first time in NHL history, neither of the two teams that played in the previous year’s Stanley Cup Finals (the Carolina Hurricanes and the Edmonton Oilers) qualified for the playoffs. For the first time since 1994, all four former WHA teams; Carolina (formerly the Hartford Whalers), Colorado (formerly the Quebec Nordiques), Edmonton, and Phoenix (formerly the Winnipeg Jets) missed the playoffs in the same year, this would not happen again until 2013. This was the only time that the Atlanta Thrashers qualified for the playoffs in their twelve years in Georgia (they became the new Winnipeg Jets in 2011).
