Liga MX, also known as Liga BBVA MX for sponsorship reasons, is a professional association football league in Mexico and the highest level of the Mexican football league system. Formerly known as Liga Mayor (1943–1949) and also as Primera División de México (1949–2012), it has 18 participating clubs, with each season divided into two short tournaments, Apertura from July to December and Clausura from January to May. The champions are decided by a final phase called "liguilla". Since 2020, promotion and relegation has been suspended, which is to last until 2026.
The league currently ranks first in CONCACAF's league ranking index. According to the IFFHS, Liga MX was ranked as the 10th strongest league in the first decade of the 21st century. According to CONCACAF, the league – with an average attendance of 25,557 during the 2014–15 season – draws the largest crowds on average of any football league in the Americas and the third largest crowds of any professional sports league in North America, behind only the NFL and MLB. It is also the fourth most attended football league in the world behind Germany's Bundesliga, England's Premier League and Spain's La Liga. Liga MX ranks second in terms of television viewership in the United States, behind the English Premier League.
América have won the league a record of 16 times, followed by Guadalajara with 12 titles and Toluca with 11 titles. In all, twenty-four teams have won the top professional division title at least once.
