The 1970 Montreal Alouettes season was the 13th season for the team in the Canadian Football League and their 25th overall. The Alouettes finished the season in third place in the Eastern Conference with a 7–6–1 record and won the Grey Cup, by defeating another third place team, the Calgary Stampeders in a rain soaked field, which both teams called disgraceful. This was Montreal's second Grey Cup, with the first being in their fourth year of existence in 1949. The 1970 season was the first season under head coachSam Etcheverry and the first under general managerRed O'Quinn.[1]
