The 2016–17 Ottawa Senators season was the 25th season of the Ottawa Senators of the National Hockey League (NHL). After failing to make the 2016 Stanley Cup playoffs, the Senators replaced their management and coaching staff, promoting Pierre Dorion to general manager, and hiring Guy Boucher and Marc Crawford and assistants to coach the team. The team would defy the predictions of much of the media by qualifying for the 2017 playoffs, and then by winning two rounds in the playoffs before losing in double overtime in game seven of the Eastern Conference Final to the eventual Stanley Cup champion Pittsburgh Penguins.
