The 2020–21 Slovak Cup was the 52nd edition of the competition. The tournament began on 25 July 2020 and the final was played on 19 May 2021.
Slovan Bratislava were the defending champions, defeating Ružomberok in the 2020 final.
Slovan won a second consecutive title, defeating Žilina in the final.
The winner of the Slovak Cup earned automatic qualification for the second qualifying round in UEFA Europa Conference League. As Slovan had already qualified for the 2021–22 UEFA Champions League as league champion, the spot was decided by the Europa Conference League play-offs, which was eventually won by Žilina.
