The 2015–16 Ottawa Senators season was the 24th season of the Ottawa Senators of the National Hockey League (NHL). The Senators, along with all other Canadian teams, failed to make the playoffs. A major trade was made during the season to bring Dion Phaneuf to the Senators and improve the team defence, but the team was not able to make a run to secure a playoff spot. Two significant faults in the team were noted by the media: the club allowed 247 goals, third-highest in the league. Secondly, the team's penalty-killing unit ranked 29th in the league. One day after the regular season, general manager (GM) Bryan Murray stepped down and assistant GM Pierre Dorion became GM. Head coach Dave Cameron and the coaching staff were fired two days later.
