Gabon competed at the 2012 Summer Olympics in London, from 27 July to 12 August 2012. This was the nation's ninth appearance at the Olympics; the nation did not participate at the 1976 Summer Olympics in Montreal and 1980 Summer Olympics in Moscow, affected by the African and the American-led boycott, respectively.
The Gabon Olympic Committee () sent the nation's largest delegation ever to the Games. A total of 24 athletes, 22 men and 2 women, competed in 5 sports. Men's football was the only team sport in which Gabon was represented at these Olympic games. Sprinter Ruddy Zang Milama was the nation's flag bearer at the opening ceremony.
Gabon left London with its first ever Olympic medal. Taekwondo jin Anthony Obame won the silver in the men's super heavyweight division, narrowly losing to Italy's Carlo Molfetta in the final.
