Ecuadorian Olympic Committee (Spanish: Comité Olímpico Ecuatoriano) sent a total of 16 athletes, 10 men and 6 women, to compete in 7 sports; there was only a single competitor in boxing, shooting, swimming, and tennis.

Five Ecuadorian athletes had previously competed in Sydney, including race walker Jefferson Pérez, who successfully made his fourth Olympic bid as the most experienced member.

Meanwhile, tennis player Nicolás Lapentti returned for a major comeback at his second Olympics after an eight-year absence, missing out the previous Games due to injury.

[2] Weightlifter and Pan American Games champion Alexandra Escobar was selected to carry the Ecuadorian flag in the opening ceremony.

Former Olympic champion and race walker Jefferson Pérez missed a chance to grab his second medal after finishing fourth in the men's 20 km walk.
