The 1964 Mexican League season was the 40th season in the history of the Mexican League. It was contested by eight teams. The season started on 26 March and finished on 16 August. Diablos Rojos del México won their second championship after finishing first with a 82–58 record, three games ahead of the Pericos de Puebla, led by manager Tomás Herrera.
The competition format was the same used since the 1952 season where the team with the best win-loss record by the end of the season would be the champion.
