Comité Olympique Marocain sent a total of 55 athletes, 47 men and 8 women, to compete in 9 sports.

The Moroccan team featured four Olympic medalists from Sydney: boxer Tahar Tamsamani, steeplechaser Ali Ezzine, middle-distance runner and top favorite Hicham El Guerrouj, and hurdler and former world champion Nezha Bidouane, who later became the nation's first ever female flag bearer in the opening ceremony.

As one of the major highlights of these Games, Hicham El Guerrouj set an Olympic historical milestone as the first ever Moroccan athlete to strike a distance double (1500–5000) since Paavo Nurmi did so in 1924, and the first to claim a gold since the 1992 Summer Olympics in Barcelona, where Khalid Skah won the men's 10,000 metres title.

Only two of them won their first bouts, including Sydney bronze medalist Tahar Tamsamani, and both were defeated in the second round to give the team a combined record of 2–7.
