The team of the Olympic Federation of Ireland, which competed at the 2020 Summer Olympics in Tokyo, represented athletes from both the Republic of Ireland and those from Northern Ireland who choose it instead of the Great Britain and Northern Ireland team. Originally scheduled to take place from 24 July to 9 August 2020, the Games were postponed to 23 July to 8 August 2021, due to the COVID-19 pandemic. It was the team's twenty-second appearance at the Summer Olympics, having attended every edition since 1924 (before then the whole of Ireland was represented by the Great Britain and Ireland team) except the 1936 Summer Olympics in Germany.

Team Ireland sent its largest-ever Olympic squad of 116 athletes to the Summer Games in Tokyo.

Equestrian

Irish equestrians qualified a full squad in both the team dressage and eventing competitions; the former by securing the second of three available berths for Group A and B at the European Championships in Rotterdam, Netherlands, and the latter by finishing among the top six nations at the 2018 FEI World Equestrian Games in Tryon, North Carolina, United States. A team of jumping riders was added to the Irish equestrian squad by winning the gold medal at the FEI Nations Cup Final in Barcelona, Spain. Tokyo 2020 would have been the first time that Ireland participated in an Olympic team dressage competition.

The Irish eventing and jumping squads were named on 21 June 2021. The dressage squad was withdrawn following a series of individual withdrawals due to a horse retirement, veterinary and medical reasons. An individual dressage place had been sought and was eventually offered in favor of Heike Holstein. James Connor and Dane Rawlins have appealed the decision to withdraw the dressage team.
