The Sierra Leone National Olympic Committee (NOC) selected two athletes via wildcards. Usually, an NOC would be able to enter up to 3 qualified athletes in each individual event as long as each athlete met the "A" standard, or 1 athlete per event if they met the "B" standard. However, since Sierra Leone had no athletes that met either standard, they were allowed to select two athletes, one of each gender, as wildcards. The Sierra Leone NOC decided to host an event in Freetown, where the fastest man and woman in the event would be selected to compete at the Athens Games. The two athletes that won and therefore were selected to compete in the Athens games were Lamin Tucker and Hawanatu Bangura. They competed in the track and field Men's 100 meters and in the Women's 100 meters respectively. Bangura was flag bearer for the opening ceremony.
