The 2007 Stanley Cup Playoffs began on April 11, 2007, and concluded on June 6, with the Anaheim Ducks defeating the Ottawa Senators to win their first Stanley Cup, becoming the first team from California to do so.
The NHL announced that the regular season salary cap rise after the initial season. The 2006–07 salary cap was increased by $5,000,000 (US) per team to bring the salary cap up to $44,000,000 (US). While the 2006–07 salary floor was increased by $8,000,000 (US) per team to $28,000,000 (US). This is the only year where the NHL salary floor raised faster than the NHL salary cap.
The Mighty Ducks of Anaheim officially shortened their name to the Anaheim Ducks prior to the season, introducing a new logo, uniforms and color scheme. This reflected a clean break from their original owners, The Walt Disney Company, who originally named the team after the movie, The Mighty Ducks upon their formation in 1993.
No NHL player had worn the jersey number 84 until Guillaume Latendresse of the Montreal Canadiens began doing so at the start of this season.
