Amhrán na bhFiann, also called The Soldier's Song in English, is Ireland's national anthem. The song has three verses, but only the choral refrain is used as the anthem.

Composed the winter 1909/10 by Patrick Heeney, and with lyrics by Peadar Kearney, it was used as marching song by the Irish Volunteers. It was sung by rebels in the General Post Office during the Easter Rising of 1916, and its popularity increased among rebels held in Frongoch internment camp after the Rising. The tune remained popular as an Army tune after the Irish War of Independence, and the Irish Civil War, and soon it was de facto widely adopted as the Irish Anthem. The official adoption came later due to song's history, and the political situation after the Civil War.
