The
Belgian Olympic and Interfederal Committee fielded a roster of 108 athletes, 70 men and 38 women, to compete across nineteen different sports at these Games; it was the nation's second-largest delegation sent to the Olympics, falling short of the record achieved in
London 2012 (111) by a few athletes. Track and field accounted for the largest number of athletes on the Belgian team, with 26 entries, while there was a single competitor each in archery, sprint canoeing, fencing, rowing, shooting, and weightlifting. The Belgian roster featured
London 2012 bronze medalists
Charline Van Snick (women's extra-lightweight judo) and sailing veteran
Evi Van Acker (Laser Radial), taekwondo fighter and former Iranian refugee
Raheleh Asemani (women's 57 kg), world-ranked tennis player
David Goffin, rising heptathlon star
Nafissatou Thiam, badminton siblings
Yuhan and
Lianne Tan, and the prominent
Borlée track and field quartet of twins and three-time Olympians
Kévin and
Jonathan, their younger brother
Dylan, and their lone sister and 2008 relay champion
Olivia, who eventually served as the nation's flag bearer in the opening ceremony. Fifteen-year-old gymnast
Senna Deriks, who helped the Belgians secure one of available berths in the women's team all-around at the Games, was the country's youngest competitor, with equestrian eventing rider and four-time Olympian
Joris Vanspringel rounding out the lineup as the oldest competitor (aged 53). Vanspringel's teammate
Karin Donckers topped the list of most experienced athletes on the Belgian roster, by becoming the country's first female to participate in her record six Olympics. The following is the list of number of competitors in the Games. Note that reserves in fencing, field hockey, football, and handball are not counted as athletes: ==Archery==
