Basketball at the 2004 Summer Olympics was the sixteenth appearance of the sport of basketball as an official Olympic medal event. It took place at the Helliniko Olympic Indoor Arena, a part of the Hellinikon Olympic Complex, in Athens, for the preliminary rounds, with the later stages being held in the Olympic Indoor Hall at the Athens Olympic Sports Complex. In Olympic basketball tournaments, 12 teams take part. The host nation (Greece in 2004) 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.

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.
