Mexicana Universal

Aspiring hopefuls, ranging from 18 to 27 years of age and a minimum height of 1.68 m (5 ft 6 in), must fulfill the organization's additional requirements and consequently vie in their respective state pageants for eligibility to participate in Nuestra Belleza México.[2] Contestants are permitted to compete for their sub-national beauty titles more than once. However, this can no longer be done once they have taken part in the national event. They may also choose to represent a different state, as long as they provide proof of having resided in it for at least the last twelve months before registration.

As of the year 2000's edition of the pageant, it is not uncommon for some states to have more than one delegate competing simultaneously. This occurs when non-winning hopefuls from select subdivisions are invited (designated) by the organization to partake in the nationwide competition, taking into consideration their potential, and to possibly make up for other states which may lack representation. Usually three or four are designated annually.[2]

Once in the national concentration, the participants engage in various events and appearances prior to the crucial preliminary competition from which a number of semi-finalists are chosen, only to be announced during the final competition. Additionally, five special awards given through sub-challenges enable the recipients an automatic pass to the semi-finals.[3] During the crowning night, the semi-finalists are evaluated by a panel of judges while vying in swimsuit and evening gown, with eliminations taking place after each of these rounds. The remaining contestants are subsequently interviewed, and the runners-up and winners are respectively announced at the conclusion of the Nuestra Belleza México telecast.

If any of the titleholders is unable to fulfill her duties, the next in turn, known as the suplente (substitute), assumes the right to represent the country abroad. The pageant, which sees over thirty of the country's most beautiful young women going head to head each year, is held a year prior to when the winners compete internationally, giving them sufficient time to prepare for their corresponding beauty events.

Below are the names of the annual titleholders of Nuestra Belleza México, the states they represented and the venue which played host to their crowning, in ascending order. Titleholders whose names appear highlighted went on to win a major international pageant. For further details, see the representatives at major international pageants section.
