The National Olympic Committee of Thailand sent the nation's smallest delegation to the Games since 1996. A total of 37 athletes, 19 men and 18 women, competed in 15 sports. Among the sports played by the athletes, Thailand marked its Olympic debut in slalom canoeing, and also, its Olympic return in archery and rowing after an eight-year absence. Four athletes received their spots in athletics and swimming by wild card entries, while the other Thai athletes won their spots by participating in various qualifying matches around the world. Four Thai athletes made their fourth Olympic appearance: pistol shooter Jakkrit Panichpatikum (the oldest athlete of the team, at age 39), badminton players Boonsak Ponsana and Saralee Thoungthongkam, and table tennis player Nanthana Komwong. Breaststroke and medley swimmer Nuttapong Ketin, the youngest male athlete of the team, was the nation's flag bearer at the opening ceremony.
Thailand, however, failed to win an Olympic gold medal for the first time since 1992, but left London with only two silver and two bronze. Taekwondo jin Chanatip Sonkham managed to repeat the nation's Olympic medal by taking the bronze in women's flyweight division. Other medals were awarded to the athletes in weightlifting, and in boxing, won by Kaeo Pongprayoon from the men's light-flyweight division.
