Athletics at the 2020 Summer Olympics were held during the last ten days of the Games. They were due to be held from 31 July – 9 August 2020, at the Olympic Stadium in Tokyo, Japan. Due to the COVID-19 pandemic, the games were postponed to 2021, with the track and field events set for 30 July – 8 August. The sport of athletics at these Games was split into three distinct sets of events: track and field events, remaining in Tokyo, and road running events and racewalking events, moved to Sapporo. A total of 48 events were held, one more than in 2016, with the addition of a mixed relay event.

The Japan National Stadium, officially the National Stadium , alternatively “Olympic Stadium” , and formerly “New National Stadium” is a multi-purpose stadium used mostly for association football in Kasumigaoka, Shinjuku, Tokyo, Japan. The facility served as the main stadium for the opening and closing ceremonies, as well as the venue for track and field athletics events at the 2020 Summer Olympics and 2020 Summer Paralympics in 2021.
