The 2005 InterLiga was a tournament organized by the Mexican Football Federation to determine which two Mexican clubs would qualify for the 2005 Copa Libertadores. That year, Mexico was granted three berths; one, designated Mexico 1, was awarded based on league performance, while the remaining two, designated Mexico 2 and Mexico 3, were decided in the InterLiga. The tournament ran from January 2 to January 12.
The group phase of InterLiga remained the same as in 2004, but the final games were changed. The top team from each group plays the second-place team from the opposite group, with both winners advancing to Copa Libertadores. Of the two final winners, the one with the highest point total during group play will be designated "Mexico 2" and automatically advance to the group stage. The other final winner will be "Mexico 3", and will enter the preliminary round of Copa Libertadores.
The tournament was played across six cities in the United States: Phoenix, Houston, Los Angeles, San Antonio, Dallas, and San Jose. Two finals were held on January 12 at Reliant Stadium in Houston.
The eight qualified clubs participated in the following groups:
Matches at Bank One Ballpark (Phoenix, Arizona)
Matches at The Home Depot Center (Carson, California)
Matches at Spartan Stadium (San Jose, California)
Matches at Alamodome (San Antonio, Texas)
Matches at Cotton Bowl (Dallas, Texas)
Matches at Reliant Stadium (Houston, Texas)
