After retiring in 2012, which Olympics did Michael Phelps compete in?

After retiring in 2012, Michael Phelps competed at the 2016 Rio Olympics.

Phelps initially stepped away from competitive swimming after the London 2012 Games, where he became the most decorated Olympian in history. He returned to training in 2014 and qualified for the U.S. team for Rio de Janeiro, his fifth Olympic Games.

At Rio 2016, Phelps served as the United States flag bearer during the opening ceremony. He won five gold medals and one silver, bringing his career Olympic total to 28 medals, including 23 golds.

A common mix-up is the 2020 Tokyo Olympics: Phelps did not compete there. Rio was his final Olympic appearance, and he announced his second retirement after the 2016 Games.
