The 2007–08 NHL season was the 91st season of operation (90th season of play) of the National Hockey League (NHL). It began on September 29, 2007, and the regular season ended April 6, 2008. The Stanley Cup playoffs ended on June 4, with the Detroit Red Wings taking the championship. The 56th NHL All-Star Game was held in Atlanta, Georgia, as the Atlanta Thrashers hosted the event at Philips Arena on January 27, 2008. The hosting by Atlanta was rescheduled from 2005, when a lockout cancelled the entire 2004–05 season.

The league announced that the regular season salary cap would be going up for the third consecutive season. The 2007–08 salary cap is being increased by US$6.3 million per team to bring the salary cap up to US$50.3 million. The salary floor is at US$34.3 million, which is 71.5% higher than the salary floor during the 2005–06 season. The season featured the debut of Reebok's new Rbk Edge hockey jerseys. This was the first league-wide uniform innovation in the history of any major North American professional sports league.^[1] Seven teams (Boston, Tampa Bay, Vancouver, Washington, Ottawa, San Jose and Columbus) unveiled new designs prior to the season's beginning.

On March 1, 2007, the NHL announced the regular season would open on September 29, 2007, with the first of back-to-back games in London at The O2 Arena. They were the first NHL regular season games ever played in Europe. Both games featured the defending Stanley Cup champion Anaheim Ducks and the Los Angeles Kings (who are owned by Anschutz Entertainment Group, the same company that owns The O2).^[2]

The official average attendance per game was 17,625 per game. However, if the two games played at The O2 Arena are counted, the number is 17,309 per game.

On September 17, 2007, the NHL announced the first outdoor game in over four years would be played between the Pittsburgh Penguins and the Buffalo Sabres at Buffalo's Ralph Wilson Stadium, home of the National Football League's Buffalo Bills, on January 1, 2008. The event—known as the AMP Energy NHL Winter Classic—was the first time an NHL regular-season game had been played outdoors in the United States, and it set an NHL attendance record of 71,217 people. The only previous outdoor NHL game was the 2003 Heritage Classic played between the Montreal Canadiens and Edmonton Oilers at Commonwealth Stadium on November 22, 2003.^[3]

During board of governors meetings held on September 18, 2007, in Chicago, cities including Las Vegas, Kansas City, Houston, Milwaukee, Quebec City, Seattle and Winnipeg were discussed as possible expansion destinations. The NHL also discussed the current "unbalanced" schedule and voted on a new schedule format at a board meeting in November, so that all teams will play each other at least once and reduce intradivisional play in the 2008–09 season, in essence returning to the scheduling structure that existed in 2003–04, and would have existed in 2004–05. The sale of the Lightning and Predators teams were not completed for board approval.^[4]

The New Jersey Devils began playing in their new arena, the Prudential Center in Newark, New Jersey. However, since the arena was not ready by the beginning of the season, they began their season with a nine-game road trip.

Inter-conference division play had the Northeast visit the Pacific, the Pacific visit the Atlantic, the Atlantic visit the Northwest, the Northwest visit the Southeast, the Southeast visit the Central and the Central visit the Northeast.

Michael Cammalleri of the Los Angeles Kings scored the first goal of the season against the Anaheim Ducks on September 29 in the opening game played in London, United Kingdom.

Richard Zednik of the Florida Panthers was severely injured after having his external carotid artery in his neck accidentally cut by the skate of teammate Olli Jokinen in a game against the Buffalo Sabres on February 10. Zednik fully recovered from the injury, but missed the remainder of the season.

The Anaheim Ducks and Ottawa Senators matched up for the first time since the 2007 Stanley Cup Finals on March 3, 2008, in Anaheim.

The Washington Capitals improved from 14th place in the previous season and last in the Eastern Conference during the first third of the 2007–08 season to finish as the third seed in the 2007–08 playoffs and winners of the Southeast Division. The turnaround was attributed mainly to the hiring of then-American Hockey League coach Bruce Boudreau, whose efforts won him the Jack Adams Award for the 2007–08 season.

The Detroit Red Wings won the Presidents' Trophy for finishing the regular season with the most points (115).

Fewer goals were scored in the regular season than in the 2006–07 season, with an average of 5.44 goals scored per game (6,691 goals over 1,230 games).^[5] Goaltenders combined for 161 shutouts.^[6]

In Canada, national rights were split between CBC and TSN. CBC aired Saturday night Hockey Night in Canada regular season games, while TSN's coverage included Wednesday Night Hockey and other selected weeknights. During the first three rounds of the Stanley Cup playoffs, TSN televised all-U.S. games while CBC aired all games involving Canadian teams. CBC then had exclusive coverage of the Stanley Cup Finals.

This was the third season of the league's U.S. national broadcast rights deals with NBC and Versus. With Versus' original three-year contract set to expire after this season, the cable network signed an extension through the 2010–11 season. Likewise, NBC announced the activation of its option to extend its broadcasting rights through the next three seasons. Versus aired regular season games generally on Monday and Tuesday nights. NBC's coverage was modified this season, with the broadcast network airing only one game nationally on selected weekends instead of televising two or three games regionally in these broadcast windows. During the playoffs, NBC had the rights to air selected weekend games during the first three postseason rounds of the Stanley Cup playoffs, and games 3–7 of the Stanley Cup Finals, while Versus televised selected first and second round playoff games, all Conference Finals games not aired on NBC, and the first two games of the Stanley Cup Finals.
