The Apertura 2023 Liga MX final phase was played between 22 November and 17 December 2023. A total of ten teams competed in the final phase to decide the champions of the Apertura 2023 Liga MX season.
On 22 May 2023, a modification for the final phase was announced at the owners assembly in Toluca; reducing the clubs from twelve to ten. The number of clubs qualifying for the quarter-finals was increased from four to six while the teams qualifying for the reclassification was reduced from six to four. The four clubs qualified for the reclassification competed in the "play-in" round, a tournament modeled after the NBA play-in tournament.
América defeated UANL 3âÂÂ0 on aggregate to win their fourteenth league title. As winners, América will face the Clasura 2024 champion in the 2024 Campeón de Campeones. Both finalists qualified for the 2025 CONCACAF Champions Cup.
The following teams qualified for the championship stage.
In the following tables, the number of appearances, last appearance, and previous best result count only those in the short tournament era starting from Invierno 1996 (not counting those in the long tournament era from 1943âÂÂ44 to 1995âÂÂ96).
The 9th place team hosts the 10th place team in an elimination game. The 7th hosts the 8th place team in the double-chance game, with the winner advancing as the 7-seed. The loser of this game then hosts the winner of the elimination game between the 9th and 10th place teams to determine the 8-seed.
