The Dublin event will be attended by the President, the Taoiseach, members of the Government; the Council of State; Dáil and Seanad Éireann; Diplomatic Corps; Judiciary and representatives from Northern Ireland.
The next-of-kin of those who died in past wars or on UN service and a wide cross-section of the community including ex-servicemen's organisations, as well as relatives of the 1916 Leaders, have also been invited.
The ceremony in Dublin is open to the public - but you need to be at The National Museum of Ireland, Decorative Arts and History, Collins Barracks before 10:15 this morning.
During the ceremony the President will lay a wreath on behalf of the people of Ireland.
