The men's 200 metres event at the 2020 Summer Olympics took place on 3 and 4 August 2021 at the Olympic Stadium. 48 athletes from 33 nations competed, including five universality places (one universality place was used in 2016). Canada earned its first gold medal in the event since 1928 and third overall, as Andre De Grasse added gold to his 2016 silver to become the 12th man to earn multiple medals in the 200 metres. Kenneth Bednarek and Noah Lyles, both of the United States, took silver and bronze as Americans reached the podium for the first time since 2008 (where they coincidentally also won two medals: a silver, and a bronze). Jamaica's three-Games gold medal streak in the event ended, with Usain Bolt having retired.
