2005–06 Calgary Flames season

The 2005–06 Calgary Flames season was the 26th NHL season in Calgary while the team celebrated its 25th season of play.

The off-season following the lockout provided ominous news for the hockey starved city of Calgary as GM Darryl Sutter announced he would not re-sign free-agent Martin Gelinas, the 2004 Stanley Cup Playoffs clutch performer, for the 2005–06 NHL season. Instead Sutter brought in three ageing veterans, Bryan Marchment, Tony Amonte and Darren McCarty, as free-agent reclamation projects to start the season. Nonetheless, the season began with high expectations following their surprising run to the 2004 Stanley Cup Finals.

The season opened with a disappointing October, as the Flames started 4–7–2 before an eight-game November winning streak propelled Calgary back into contention in the National Hockey League's Northwest Division. The Flames would battle the Colorado Avalanche down the stretch, ultimately finishing eight points ahead of both Colorado and the Edmonton Oilers to capture the team's sixth division crown in franchise history.

However, the playoffs proved the team was missing the "killer instinct" necessary for playoff success, as they fell in the first round to the Mighty Ducks of Anaheim in seven games.

Star goaltender Miikka Kiprusoff proved that 2003–04 was no fluke, leading the NHL in shutouts and goals against average while setting a franchise record for wins with 42. Kiprusoff's exploits would win him the Vezina Trophy and William M. Jennings Trophy, along with being named a first team all-star. Kiprusoff was also a finalist for the Hart Trophy.
