Argentina, led by NBA standouts like Manu Ginóbili and Luis Scola, won the country's first and only gold medal in the event.
In Olympic basketball tournaments, 12 teams take part. The host nation automatically receives a berth in the tournament. By winning the two World Championship tournaments in 2002, FR Yugoslavia, now named Serbia and Montenegro, also put a team into the men's tournament and the United States a team in the women's tournament.
The remaining 10 spots in each tournament were allocated by the five Olympic zones. Each of these zones held its own tournaments to select its entries in the Olympic tournament. Africa was allocated one spot in each of these, Oceania was allocated two apiece, and Europe was allocated three. Furthermore, the Americas were allocated three teams for the men's tournament and just one in the women's tournament, whereas Asia was allocated just one in the men's tournament and three in the women's tournament.

Qualification

A National Olympic Committee may enter just one men's team with 12 players, and just one women's team with 12 players in the regional tournaments. The reigning world champions and the host country qualify automatically, as do the winners of the five continental championships, plus the runner-up and third place teams from the Americas and Europe competitions, and the runner-up Oceania in the men's tournament. For the women's tournament, the extra teams consisted of the runner-up and third place teams from Asia and Europe, and the runner-up from Oceania.
