The 1923–24 Irish Cup was the 44th edition of the Irish Cup, the premier knock-out cup competition in Northern Irish football.
Queen's Island won the tournament for the 1st time, defeating Willowfield 1–0 in the final at Windsor Park. While another team called Queen's Island founded in 1881 had previously won the cup in 1882, this was the only time the Queen's Island team founded in 1920 would appear in an Irish Cup final.
