The 2014–15 Liga MX season (known as the Liga BBVA Bancomer MX for sponsorship reasons) was the 68th professional top-flight football league season in Mexico.
Atlante was relegated to the Ascenso MX after accumulating the lowest coefficient over the past three seasons.
Atlante was relegated and replaced by the Apertura 2013 Ascenso MX champion Leones Negros, after defeating in a promotional play-off the Clausura 2014 title defenders Estudiantes Tecos.
The regular season began on July 18, 2014, and ended on November 23, 2014.
León were the defending champions, having won the 2013 Apertura and 2014 Clausura tournaments.
