The 2021–22 Irish Cup (known as the Samuel Gelston's Whiskey Irish Cup for sponsorship purposes) was the 142nd edition of the Irish Cup, the premier knockout cup competition in Northern Irish football since its inauguration in 1881. The competition began on 7 August 2021 and concluded with the final at Windsor Park, Belfast on 7 May 2022.

Linfield were the defending champions, having defeated Larne 2–1 in the previous season's final. This season, they were defeated by Larne in the second round.

Crusaders were the winners, defeating Ballymena United 2–1 in the first ever meeting between the two teams in the final, and qualified for the 2022–23 UEFA Europa Conference League first qualifying round.

Format and schedule 128 clubs entered this season's competition. This was a large increase on the 26 entrants for the previous season's competition, which was played in a condensed format as a result of the COVID-19 pandemic in Northern Ireland. This season, the stages of the cup were renamed. The first four rounds will now be known as qualifying rounds, with what was historically known as the fifth round now becoming the first round of the main competition. 104 clubs entered the draw for the first qualifying round. 80 of them were drawn to face each other in 40 ties, with the remaining 24 given byes into the second qualifying round. After two further knockout rounds, the eight winners from the fourth qualifying round will join the 24 clubs from the NIFL Premiership and NIFL Championship in the first round of the main competition.
