2002–03 Ottawa Senators season

The 2002–03 Ottawa Senators season saw the Senators reach the highest point in the playoffs until the 2006–07 season. They were eliminated by the New Jersey Devils, the eventual Stanley Cup winning team in the Eastern Conference final. On top of their larger success, with their total 113 points they won the Presidents' Trophy, the Northeast Division title and the Eastern Conference title.

After their long history of debt problems, the Senators filed for bankruptcy on January 9, 2003. They continued regular season play after receiving emergency financing from the NHL. Despite the off-ice problems, they had a successful year, compared to their early day woes. The Presidents' Trophy awarded to the Senators made them the first Canadian team to win it since the Calgary Flames in their championship season of 1989, and the first Eastern Conference team to win it since the New York Rangers' title in the 1994 Stanley Cup Finals. In the playoffs, they defeated their former teammate Alexei Yashin and his New York Islanders, then the Philadelphia Flyers before coming within one game of making it into the Finals, falling to the New Jersey Devils.

Right winger Marian Hossa led Ottawa in scoring, just eclipsing Yashin's previous record of 44 goals. Without the goaltending issues that had plagued Senators teams of the past, Patrick Lalime showed one of his best seasons, with career bests in goals against average (GAA) and wins.
