Mexico at the 2012 Summer Olympics
Mexico competed at the 2012 Summer Olympics in London, from 27 July to 12 August 2012. This was the nation's twenty-second appearance at the Olympics since its debut in 1900. Comité Olímpico Mexicano sent a total of 102 athletes to the Games, 64 men and 38 women, to compete in 23 sports. Men's football was the only team sport in which Mexico was represented at these Olympic Games. There was only a single competitor in badminton, sprint canoeing, and table tennis.
The Mexican team featured several medal prospects for London, including taekwondo jin and defending champion María Espinoza, who was the nation's flag bearer at the opening ceremony. Equestrian show jumper Jaime Azcárraga, who had competed in Olympics since 1984, marked his return in London after a twenty-year absence and was also the oldest member of the team, at age 52. Laser Radial sailor Tania Elías Calles and windsurfer David Mier, on the other hand, competed at their fourth Olympics.
This was Mexico's most successful Olympics where it was not the host nation, winning a total of 8 medals, and surpassing their record from Los Angeles and Sydney by a single medal. Three of these medals were awarded to the athletes in diving, and two in archery for the first time. Among the nation's medalists were springboard diver Laura Sánchez, who won Mexico's first Olympic medal for a female in an individual event. Meanwhile, taekwondo jin María Espinoza and platform diver Paola Espinosa became the first Mexican women in history to win a total of two Olympic medals. Mexico also set a milestone in its team sports, as the men's football team won its first ever Olympic gold medal in the final match against Brazil.
