Mexico competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016. This was the nation's twenty-third appearance at the Summer Olympics. The Mexican Olympic Committee () sent the nation's largest delegation to the Games since 1972, with a total of 124 athletes, 80 men and 44 women, competing across 26 sports.

Mexico left Rio de Janeiro with five medals (three silver and two bronze), failing to win a single gold for the first time since the 2004 Summer Olympics in Athens. Among the medalists were race walker María Guadalupe González, semi-pro boxer Misael Rodríguez (men's middleweight), and modern pentathlete Ismael Hernández, who became the first ever Mexican to ascend the Olympic podium in his signature sport. Diver Germán Sánchez picked up his first individual medal at the Games with a silver in the men's platform, following a runner-up effort with his synchronized diving partner Iván García from London 2012. Taekwondo fighter María Espinoza made history as the first Mexican female to complete a full set of medals in three different Games, adding a silver to her Olympic career haul in the women's +67 kg.

Apart from the success and historic firsts of the medalists, several Mexican athletes reached further to the finals of their respective sporting events, but came closest to the podium finish. Among them were shooter Alejandra Zavala (fourth, women's air pistol), weightlifter Bredni Roque (fourth, men's 69 kg), former Youth Olympian Diego del Real (fourth, hammer throw), diving veteran Paola Espinosa (fourth, women's platform), and archer Alejandra Valencia (fourth, women's individual recurve).

Competitors The Mexican Olympic Committee (, COM) fielded a team of 124 athletes, 80 men and 44 women, across 26 sports at the Games. It was the nation's largest delegation sent to the Olympics since 1972, surpassing the previous mark by an increase of 22 athletes.

Football and volleyball, both of which played by men, were the only team-based sports in which Mexico qualified for the Games, with the latter having returned to the Olympic tournament after more than four decades. For individual-based sports, Mexico made its Olympic debut in mountain biking and golf (new to the 2016 Games), as well as its return to men's beach volleyball and tennis after 16 years.

Seven of the nation's Olympic medalists from London 2012 returned, including diving tandem Iván García and Germán Sánchez (men's synchronized platform), as well as their female counterparts Paola Espinosa and Alejandra Orozco (women's synchronized platform); archer and three-time Olympian Aída Román, taekwondo fighter María Espinoza, and football team captain Oribe Peralta, who helped the Mexicans score two goals for a shocking gold-medal victory over Brazil in the men's tournament final. Windsurfer David Mier headed the full roster of Mexican athletes by participating in his fifth consecutive Olympics as the most experienced competitor. He was followed by Espinosa and heavyweight judoka Vanessa Zambotti, both of whom vied for their fourth straight Games.

18-year-old springboard diver Melany Hernández was Mexico's youngest competitor, with dressage rider and two-time Olympian Bernadette Pujals rounding out the field as the oldest competitor (aged 48).
