Cook Islands at the 2020 Summer Olympics

The Cook Islands competed at the 2020 Summer Olympics in Tokyo. Originally scheduled to take place from 24 July to 9 August 2020, the Games were postponed to 23 July to 8 August 2021, because of the COVID-19 pandemic. It was the nation's ninth consecutive appearance at the Summer Olympics. The Cook Islands sent their first delegation to the Olympics at the 1988 Summer Olympics in Seoul, South Korea. In the Games, the country sent six athletes to the Olympics across three sports. They were Alex Beddoes in athletics, Jane Nicholas, Kohl Horton, and Jade Tierney in canoeing, and Wesley Roberts and Kirsten Fisher-Marsters in swimming. Roberts and Fisher-Marsters were the flagbearers at the opening ceremony, and there were no flagbearers at the closing ceremony. The Cook Islands did not win any medals during the Tokyo Olympics.
