Miss Mexico is a Mexican national beauty pageant held annually since 1952. It is responsible for selecting the country's delegates to three of the most relevant international beauty contests, Miss Universe, Miss World and Miss International
The Miss Mexico Organization has produced two Miss Universe titles for Mexico: Miss Universe 1991 and 2010. It is directed by Lupita Jones, the first Mexican Miss Universe in 1991. Miss Mexico is managed by Nuestra Belleza México since 1994, replacing Señorita México from 1952 to 1993.
Aspiring hopefuls ranging from 18 to 23 years of age and a minimum height of 1.68 m (5 ft 6 in) must fulfill the organization's additional requirements and vie in their respective state pageants for eligibility to participate in Nuestra Belleza México (Miss Mexico). Contestants are permitted to compete for their sub-national beauty titles more than once, as long as they still meet the age limit. This, however, can no longer be done once they have taken part in the national event, be it even as a designated contestant. As of 2000, it is not uncommon for some administrative divisions of the country to have more than one delegate competing simultaneously. This generally occurs when non-winning state pageant hopefuls are invited (designated) by the organization to partake in the national competition, either because they believe in the contestants' potential, or simply because other states lack representation. Over thirty of Mexico's most beautiful young women collide each year.
