The 1969–70 season was Manchester City's fourth consecutive season in the top tier of English football. The season marked a significant one as the club won its first double, which included its maiden League Cup and European trophy, being the European Cup Winners' Cup. They also became the first English side to complete a major domestic and European double. The club would not win another European trophy until 53 years later, in the 2023 UEFA Champions League Final.

The League Cup victory, combined with the First Division, FA Cup and Charity Shield success of the previous two seasons meant City became the first English club to win all four major domestic trophies.
