The 2015–16 NHL season was the 99th season of operation (98th season of play) of the National Hockey League (NHL). Thirty teams competed in 82-game regular season schedules from October 7, 2015 to April 10, 2016.

The 2016 Stanley Cup playoffs following the regular season began on April 13 and ended June 12 with the Pittsburgh Penguins winning their fourth Stanley Cup. None of the seven Canadian-based teams qualified for the playoffs; this was the second season in league history that the playoff field consisted of only United States-based teams. The only other time in league history that no Canadian teams qualified for the postseason was in 1970.

Salary cap

In December 2014, commissioner Gary Bettman told teams that he projected the salary cap to increase to at least $73 million for the 2015–16 season, citing the fluctuating value of the Canadian dollar. The cap was ultimately set at $71.4 million.

Rule changes

Rule changes approved by the NHL Board of Governors on June 24, 2015, include:

2015–16 NHL season

3-on-3 overtime: Overtime during the regular season will now have three skaters per side, instead of the 4-on-4 overtime system that had been used since 1999–2000. However, if there are carry-over penalties from the third period to overtime, a side is still guaranteed to have at least three skaters and the man-advantage will be adjusted accordingly (e.g. a 5-on-4 power play at the end of regulation will be converted to a 4-on-3 one at the start of overtime). The Board of Governors implemented 3-on-3 overtime to help decrease shootouts. Jason Garrison of the Tampa Bay Lightning scored the first 3-on-3 overtime goal on October 9, 2015 for a 3-2 victory over the Philadelphia Flyers. Expanded video review with coach's challenge: Video review has been expanded to include a coach's challenge, similar to the system used by the NFL since 1999: Like the NFL, each challenge will require the use of a team's timeout. If the challenge is successful, the timeout is restored. Teams may only challenge the following situations: Whether a goal called on the ice should have been disallowed because the attacking team was offside or interfered with the goaltender; Whether a disallowed goal, called on grounds of goalkeeper interference, should instead be overturned because either: there was no actual contact between the attacking player and the goalie the attacking player was actually pushed or fouled by a defender into the goalie the attacking player's position in the crease did not actually impair or impact the goalie's play Inside the final minute of regulation, and during overtime, all reviews that would otherwise be subject to the coach's challenge will instead be initiated by the NHL's Situation Room in Toronto All reviews that are subject to the coach's challenge will be conducted by the on-ice officials on an ice-level tablet monitor instead of the Situation Room. All reviews involving whether the puck entered the net will still be initiated by the Situation Room. New faceoff rule: During faceoffs not at center-ice, the player who is on the defensive side of the red line will now be required to put his stick down first. For faceoffs at the center-ice dot, the visiting player will still be the first one to place down his stick. This rule change, giving the attacking team a slight advantage during faceoffs (as opposed to giving this advantage to the home team all the time), is intended to help increase puck-possession time and potentially more goals.

Expansion bids

For the second time since 2000, the league ended a moratorium on potential expansion teams and began accepting bids for potential expansion teams that, if approved, would begin play in the 2017–18 season. During the 2015 offseason, two ownership groups offered bids: Quebecor, which planned on reviving the Quebec Nordiques at a new arena in Quebec City, Quebec, and Bill Foley's Black Knight Sports & Entertainment, which intended to place an expansion team at a new arena in Las Vegas, Nevada. The league concluded the vetting process on September 4, 2015, with a final decision to follow in June 2016.
