Iceland competed at the 2004 Summer Olympics in Athens, Greece, from 13 to 29 August 2004. Icelandic athletes have competed at every Summer Olympic Games in the modern era since 1912, except for four occasions.

The National Olympic and Sports Association of Iceland sent a total of 26 athletes, 21 men and 5 women, to compete in 5 sports, including men's handball, the nation's only team-based sport at these Olympic games. Seven Icelandic athletes had previously competed in Sydney, including swimmer Örn Arnarson, who finished fourth in the men's 200 m backstroke. Handball player Guðmundur Hrafnkelsson, who competed in his third Olympics since 1988 and helped his team set a remarkable comeback to the Games after an eight-year absence, was appointed by the committee to become the nation's flag bearer in the opening ceremony.^[1]

Iceland failed to win an Olympic medal for the first time since 1996, although pole vaulter Þórey Edda Elísdóttir achieved a best result for the team at these Games with a fifth-place finish.

Icelandic athletes have so far achieved qualifying standards in the following athletics events (up to a maximum of 3 athletes in each event at the 'A' Standard, and 1 at the 'B' Standard).^[2][3]
