Antigua and Barbuda at the 2016 Summer Olympics

Antigua and Barbuda competed at the 2016 Summer Olympics in Rio de Janeiro, Brazil, from 5 to 21 August 2016. This was the nation's tenth appearance at the Summer Olympics.

The Antigua and Barbuda Olympic Association sent the nation's largest roster to the Games for the first time since 1996. A total of nine athletes, seven men and two women, were selected to compete only in athletics and swimming, due to the presence of the men's 4 × 100 m relay team. Being the most experienced member of the team, sprinter Daniel Bailey was appointed to carry the nation's flag for the third time in the opening ceremony.

Antigua and Barbuda, however, has yet to win its first ever Olympic medal.
