The 1990–91 Calgary Flames season was the 11th National Hockey League season in Calgary. The Flames entered the season with a new coach, as they replaced Terry Crisp with Doug Risebrough. Crisp coached 277 games with the Flames over three years, and his .669 regular season winning percentage remains a Flames record. Four Flames represented the Campbell Conference at the 1991 All-Star Game: forward Theoren Fleury, defencemen Al MacInnis and Gary Suter and goaltender Mike Vernon. Additionally, MacInnis was named to the first All-Star team for the second season in a row.
