List of Mexican football champions
The Mexican football champions are the national champions of the Liga MX, which is the highest level of the Mexican football league system. Formerly known as Liga Mayor from 1943 to 1949, and also as Primera División de México from 1949 to 2012. The first season in the professional era began in 1943.
Since the 1970–71 season, the final phase called "liguilla" has been held to define the champions. Since the 1996–97 season, two champions are crowned each year, starting with the Invierno and Verano tournaments (1996–2002), later renamed as the Apertura and Clausura tournaments (2002–present).
