The 1880–81 Irish Cup was the inaugural edition of the Irish Cup, the premier knock-out cup competition in Irish football. The competition began on 5 February 1881 with the first round and ended on 9 April 1881 with the final. Moyola Park were the first winners of the competition, and they have never won it since.
The competition was played in a straight knock-out format. If a match ended level at full time, a replay was required to decide the winner. The first Irish Cup replay was between Cliftonville and Knock on 26 March 1881. William Morrow of Moyola Park scored the first goal in an Irish Cup final during his club's 1–0 win over Cliftonville to lift the trophy.
