It was the nation's largest delegation sent to the Olympics since 2000, increasing by a third of its full roster size at London 2012. Among the sports represented by the nation's athletes, Nigeria marked its Olympic debut in rowing, as well as its return to swimming and men's football after an eight-year hiatus. Apart from the men's football squad, Nigeria also returned to the Olympic scene in men's basketball for the second consecutive time.
