2019–20 Liga MX season

The 2019–20 Liga MX season (known as the Liga BBVA MX for sponsorship reasons) was the 73rd professional season of the top-flight football league in Mexico. The season was divided into two championships—the Torneo Apertura and the Torneo Clausura—each in an identical format and each contested by the same nineteen teams. The Apertura tournament began on 19 July 2019.

On 15 March 2020, the Mexican Football Federation suspended the Clausura seasons of Liga MX, Ascenso MX and Liga MX Femenil indefinitely due to the coronavirus pandemic.

On 22 May 2020, the season was cancelled due to the COVID-19 pandemic affecting the country. While no official champion was crowned for that season officially, Cruz Azul and León were awarded the Clausura champions and runners-up positions ("MEX2" and "MEX4") respectively for purposes of filling the 2021 CONCACAF Champions League, as the first and second-placed teams of the regular season at the time of suspension.

Teams, stadiums, and personnel
The following nineteen teams competed this season. Atlético San Luis was promoted from the Ascenso MX. Veracruz was to be relegated to the Ascenso MX initially after accumulating the lowest point coefficient last season, but instead they offered to pay MXN$120 million to remain in Liga MX. The team, however, was eventually disaffiliated by the FMF at the end of the Apertura 2019 tournament. Lobos BUAP's franchise in the first division was purchased by FC Juárez. Lobos BUAP will be able to participate in the Ascenso MX but will remain frozen for one year.
