In Ireland, the National Day of Commemoration () commemorates all Irish people who died in past wars or United Nations peacekeeping missions. It occurs on the Sunday nearest 11 July (see Irish Calendar), the anniversary of the date in 1921 that a truce was signed ending the Irish War of Independence.|group="fn" The principal ceremony is held at the Royal Hospital Kilmainham, Dublin, Ireland.|group="fn"

Commemoration of the Irish War of Independence was muted by the bitterness of the Irish Civil War that followed from it. The preceding 1916 Easter Rising against British rule in Ireland was the focus, with Easter Day considered the "National Day of Commemoration". There was a major parade each Easter until 1971, when the Troubles in Northern Ireland made the commemoration of the earlier Irish Republican rebels more problematic in symbolism.
