The Apertura 2017 Copa MX was the 78th staging of the Copa MX, the 50th staging in the professional era and is the eleventh tournament played since the 1996–97 edition. This tournament began on 25 July 2017 and was originally scheduled to end on 1 November 2017. Due to the 2017 Puebla earthquake, the tournament was postponed in the Round of 16 phase, pushing the end of the tournament to 21 December 2017. The final was held at Estadio BBVA Bancomer in the Monterrey suburb of Guadalupe with the home team Monterrey defeating Pachuca 1–0 to win their second title. As winners, Monterrey earned a spot to face the winners of the Clausura 2018 edition, in the 2018 Supercopa MX.
Participants
The tournament will feature all Liga MX clubs as well as ten Ascenso MX clubs. Due to the new format of the CONCACAF Champions League, Mexican clubs do not begin their participation until February, thus the teams qualified to 2017–18 CONCACAF Champions League will participate in this season's Copa MX.
Draw
The draw for the tournament took place on June 6, 2017 in Cancún, Quintana Roo, Mexico. 27 teams were drawn into nine groups of three, with each group containing one team from each of the three pots. Clubs in Pot [|1] were drawn to be the seed of each group according to the order of their drawing. That is, the first club that was drawn is seed of Group 1, the second drawn is seed of Group [|2] and so on and so on. The Liga MX teams in Pot 1 are the teams who ended 1–5 in the 2016–17 Liga MX Aggregate table The Ascenso MX teams in Pot 1 are the four best possible teams in the 2016–17 Ascenso MX Aggregate table. Zacatepec Siglo XXI who ended fourth, were replaced by Oaxaca, who ended fifth, due to the club's disappearance. Pot 2 contained Liga MX clubs who ended 6–9 in the Aggregate table and Ascenso MX clubs who ended 6–10 in the Aggregate table. Coras, who ended tenth in the Aggregate table, moved to Zacatepec, Morelos and became the new Zacatepec franchise. Pot [|3] contained Liga MX clubs who ended 10–17 in the Aggregate table.
