Argentina is scheduled to compete at the 2020 Summer Olympics in Tokyo from 24 July to 9 August 2020. Since the nation's official debut in 1900, Argentine athletes have competed in every edition of the Summer Olympic Games, except the 1904 Summer Olympics in St. Louis, the 1912 Summer Olympics in Stockholm, and the 1980 Summer Olympics in Moscow because of its support for the United States-led boycott.
Argentine sailors qualified one boat in each of the following classes through the 2018 Sailing World Championships, the class-associated Worlds, the 2019 Pan American Games, and the continental regattas.
