The 2021–22 Belgian Cup, called the Croky Cup for sponsorship reasons, was the 67th season of Belgium's annual football cup competition. The competition began on 25 July 2021 and ended with the final on 18 April 2022. The winners of the competition qualified for the 2022–23 UEFA Europa League play-off round.
The competition consists of one preliminary round, followed by ten proper rounds. All rounds were single-match elimination rounds, with the exception of the semi-finals which are again held over two legs. When tied after 90 minutes in the first three rounds, penalties were taken immediately. From round four, when tied after 90 minutes first an extra time period of 30 minutes was played, then penalties were taken if still necessary.
