Argentina at the 2004 Summer Olympics
Argentina competed at the 2004 Summer Olympics in Athens, Greece, from 13 to 29 August 2004. This was the nation's twenty-first appearance at the Olympic Games, except for three different editions. Argentina did not attend the 1904 Summer Olympics in St. Louis, the 1912 Summer Olympics in Stockholm, and the 1980 Summer Olympics in Moscow, because of its support for the United States-led boycott. The sailor Carlos Espínola was the nation's flag bearer at the opening ceremony. 152 competitors, 106 men and 46 women, took part in 86 events in 22 sports.
The total medal count of six, marked the best performance by Argentina since the 1948 Summer Olympics, earning their first gold medals since the 1952 Summer Olympics and their best position in the medal table up to that point, at 35th place overall.
