Saint Lucia at the 2020 Summer Olympics

Saint Lucia competed at the 2020 Summer Olympics in Tokyo, Japan. 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 seventh consecutive appearance at the Summer Olympics. The nation was seeking its first Olympic medal; Levern Spencer's 6th-place finish in the 2016 high jump was Saint Lucia's best result to date at the time of this Olympics.

The country's planning for the 2020 Games began shortly after the conclusion of the 2016 Summer Olympics, with Saint Lucia Olympic Committee president Fortuna Belrose noting that some athletes had already expressed interest and submitted programmes. Saint Lucia's Olympic hopefuls include Spencer (who would be a four-time Olympian), Jeanelle Scheper (a 2016 Olympian), Albert Reynolds, Sandisha Antoine, and Julien Alfred. The COVID-19 pandemic has affected preparations, training, and qualification efforts; Belrose and the SLOC have committed to supporting athletes in qualifying for the postponed Games.
