The Mexican team featured three Olympic medalists from Sydney: race walker Noé Hernández, taekwondo jin Víctor Estrada, and diver Fernando Platas, who reprised his role to carry the national flag for the second time in the opening ceremony, after winning the silver in men's springboard.

Mexico left Athens with a total of four medals (three silver and one bronze), failing to win a gold for the first time since 1996.

Sprinter Ana Guevara set the nation's historical milestone as the first ever female Mexican to claim an Olympic silver medal in track and field.

Two Mexican athletes qualified to compete in the modern pentathlon event through the 2003 Pan American Games in Santo Domingo, Dominican Republic.
