Gymnastics at the 2020 Summer Olympics – Men's horizontal bar

This will be the 25th appearance of the event, which is one of the five apparatus events held every time there were apparatus events at the Summer Olympics (no apparatus events were held in 1900, 1908, 1912, or 1920).

A National Olympic Committee (NOC) could enter up to 6 qualified gymnasts: a team of 4 and up to 2 specialists. A total of 98 quota places are allocated to men's gymnastics.

The 12 teams that qualify will be able to send 4 gymnasts in the team competition, for a total of 48 of the 98 quota places. The top three teams at the 2018 World Artistic Gymnastics Championships (China, Russia, and Japan) and the top nine teams (excluding those already qualified) at the 2019 World Artistic Gymnastics Championships (Ukraine, Great Britain, Switzerland, the United States, Chinese Taipei, South Korea, Brazil, Spain, and Germany) earned team qualification places.

The remaining 50 quota places are awarded individually. Each gymnast can only earn one place, except that gymnasts that competed with a team that qualified are eligible to earn a second place through the 2020 All Around World Cup Series. Some of the individual events are open to gymnasts from NOCs with qualified teams, while others are not. These places are filled through various criteria based on the 2019 World Championships, the 2020 FIG Artistic Gymnastics World Cup series, continental championships, a host guarantee, and a Tripartite Commission invitation.

Each of the 98 qualified gymnasts are eligible for the pommel horse competition, but many gymnasts do not compete in each of the apparatus events.

The COVID-19 pandemic delayed many of the events for qualifying for gymnastics. The 2018 and 2019 World Championships were completed on time, but many of the World Cup series events were delayed into 2021.

The top 8 qualifiers in the qualification phase (limit two per NOC) advance to the apparatus final. The finalists perform an additional exercise. Qualification scores are then ignored, with only final round scores counting.

The competition is held over two days, Saturday, 24 July and Tuesday, 3 August. The qualifying round (for all men's gymnastics events) is the first day; the apparatus final is on the second day.[1]
