Madagascar at the 2020 Summer Olympics

Madagascar sent a delegation that competed at the 2020 Summer Olympics in Tokyo.

Six athletes from Madagascar were selected for the Games, competing in four different sports. Damiella Nomenjanahary and Éric Andriantsitohaina were chosen to be Madagascar's flag bearers during the Parade of Nations of the opening ceremony. There were no Malagasy athletes at the closing ceremony.
