2003–04 Calgary Flames season

The 2003–04 Calgary Flames season was the 24th National Hockey League season in Calgary, and the 32nd for the franchise in the NHL. The Flames ended a seven-year playoff drought, qualifying for the post-season for the first time since 1996. The Flames defeated three division winners en route to an appearance in the 2004 Stanley Cup Finals. The Flames were defeated in the finals by the Tampa Bay Lightning in seven games. The run to the finals captured the imagination of the city, while the Red Mile celebrations gained international attention for the "Mardi Gras-like" atmosphere as up to 80,000 people celebrated in the streets after each playoff game.

Head coach Darryl Sutter succeeded Craig Button as the Flames' general manager. Sutter made numerous changes to the roster as he worked to remake the Flames into a fast, physical club. Chris Drury was dealt to Buffalo for Rhett Warrener and Steve Reinprecht before the season began. A knee injury to starting goaltender Roman Turek led Sutter to trade for Miikka Kiprusoff, a player he knew from his days with the San Jose Sharks. Kiprusoff responded to the deal by posting an NHL record low Goals Against Average of 1.69.

The Flames were led offensively by Jarome Iginla, who tied Ilya Kovalchuk and Rick Nash for the league lead with 41 goals as the trio shared the Rocket Richard Trophy. Iginla represented the Flames at the 54th National Hockey League All-Star Game in Minnesota, and was named a second team all-star for his performance during the season. Iginla's charity work and leadership both on and off the ice led to his also being awarded the King Clancy Memorial Trophy and NHL Foundation Player Award.
