Samoa at the 2020 Summer Olympics

Samoa 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 tenth consecutive appearance at the Summer Olympic Games, for four of which it competed under the name Western Samoa.

This meant that only Samoan athletes based overseas could compete in the games. For the first time since its debuted in 1984, none of the Samoan weightlifters had been qualified.
