The 2020 Stardom Cinderella Tournament (スターダムシンデレラトーナメント2020, Sutādamushindereratōnamento 2020) was the sixth annual professional wrestling single-elimination tournament promoted by World Wonder Ring Stardom in Tokyo, Japan. The event took place on March 24, 2020, with a limited attendance due in part to the ongoing COVID-19 pandemic at the time.^[2]

The show featured thirteen Cinderella Tournament matches and a dark match with scripted storylines, where wrestlers portray villains, heroes, or less distinguishable characters in the scripted events that built tension and culminate in a wrestling match or series of matches.^[3] The matches can be won by pinfall, submission or elimination over the top rope. A time-limit draw or a double elimination means a loss for each competitor.

The tournament was composed by 16 competitors including the champions. It was the last event to conclude in a single day.^[8]
