The Calgary Flames are a professional ice hockey team based in Calgary, Alberta. They compete in the National Hockey League as a member of the Pacific Division of the Western Conference. The club is the third major professional ice hockey team to represent the city of Calgary, following the Calgary Tigers and Calgary Cowboys. The Flames are one of two NHL franchises in Alberta; the other is the Edmonton Oilers. The cities' proximity has led to a rivalry known as the "Battle of Alberta". The team was founded in 1972 in Atlanta as the Atlanta Flames until relocating to Calgary in 1980. The Flames played their first three seasons in Calgary at the Stampede Corral before moving into their current home arena, the Scotiabank Saddledome, in 1983. In 1985–86, the Flames became the first Calgary team since the 1923–24 Tigers to compete for the Stanley Cup. In 1988–89, the Flames won their first and only championship. The Flames' unexpected run to the 2004 Stanley Cup Finals gave rise to the Red Mile, and in 2011 the team hosted and won the second Heritage Classic outdoor game.
