National Day of Commemoration ceremonies have been held at Collins Barracks in Dublin, as well as at several other locations across the country.
The event honours all Irishmen and Irishwomen who died in past wars or on service with the United Nations.
In line with the Covid-19 restrictions, the ceremony at Collins Barracks was closed to the public.
President Michael D Higgins laid a wreath at the event, which was also attended by the Taoiseach Micheál Martin and members of the Cabinet.
The public from both parts of the island of Ireland were thanked for their efforts during the pandemic as well as frontline workers from all parts of civic life.
All those who lost their lives due to Covid-19 were also remembered.
