The 2019–20 Ascenso MX season was a two-part competition: Apertura 2019 and Clausura 2020, which were the final two seasons of Ascenso MX, the second-tier football league of Mexico. Apertura began on 1 August 2019. On April 17, Liga MX President Enrique Bonilla announced the termination of the remainder of the Clausura 2020 tournament. Two reasons were the COVID-19 pandemic and the league's lack of financial resources. On 22 May 2020 the Clausura season was cancelled and no champion will be crowned. With this announcement there would be no promotion or regulation for six seasons.
