Vietnam competed at the 2012 Summer Olympics in London, from July 27 to August 12, 2012. This was the nation's eighth appearance at the Olympics, having missed the 1984 Summer Olympics in Los Angeles, because of the Soviet boycott.

The Vietnam Olympic Committee (VOC) sent the nation's largest delegation to the Games since 1980. A total of 18 athletes, 6 men and 12 women, competed in 11 sports. For the first time in its Olympic history, Vietnam was represented by more female than male athletes. This was also the youngest delegation in Vietnam's Olympic history, with half under the age of 24, and many of them were expected to reach their peak in time for the 2016 Summer Olympics in Rio de Janeiro. Sixteen athletes competed in their first Olympics, including épée fencer Nguyễn Tiến Nhật, who was the nation's flag bearer at the opening ceremony.

Despite fielding its largest delegation to these games, Vietnam, however, failed to win a single medal. Pistol shooter Hoàng Xuân Vinh and weightlifter Trần Lê Quốc Toàn narrowly missed out on Olympic medals in London, after finishing fourth in their respective sporting events.

In 2020, after the disqualification one athlete in a weightlifting men's 56 kg event, the bronze medal in this event was redistributed to Trần Lê Quốc Toàn.
