The 2003–04 Toronto Maple Leafs season, the club's 87th season of existence and 77th as the Maple Leafs, saw the team finish in second place in the Northeast Division with a record of 45 wins, 24 losses, 10 ties and three overtime losses for 103 points. It was the highest point total in franchise history, beating out the 100 points earned by the 1999–2000 team. In the playoffs Leafs defeated their provincial rivals, the Ottawa Senators, in seven games in the Conference Quarterfinals before falling to the Philadelphia Flyers four games to two in the Conference Semifinals. The Leafs did not qualify for the playoffs again until the 2012–13 season, and would not win another playoff series until the 2022–23 season. This still remains the last season the Leafs would win a Game 7 of a playoff series.

On June 27, 2003, it was announced Pat Quinn would relinquish his dual roles as the team’s general manager and head coach and solely focus on coaching. John Ferguson Jr. was named the team’s new general manager on August 29.
