Simone Biles will conclude her golden Games by carrying the flag for the United States team at the Rio 2016 closing ceremony.
The 19-year-old topped the podium four times in Brazil, collecting five medals in total, and is excited to play her part on Sunday.
"It's an incredible honour to be selected as the flag bearer by my Team USA team-mates," said Biles.
"This experience has been the dream of a lifetime for me and my team and I consider it a privilege to represent my country, the United States Olympic Committee and USA Gymnastics by carrying our flag.
"I also wish to thank the city of Rio de Janeiro, and the entire country of Brazil, for hosting an incredible Games."
Biles marked her Olympic debut with gold in the team and individual all-round, vault and floor exercise, while also taking bronze on the balance beam.
