Genealogical Office

The Genealogical Office is an office of the Government of Ireland containing genealogical records. It includes the Office of the Chief Herald of Ireland (Irish: Príomh Aralt na hÉireann), the authority in Ireland for heraldry. The Chief Herald authorises the granting of arms to Irish bodies and Irish people, including descendants of emigrants. The office was constituted on 1 April 1943 as successor to the Ulster King of Arms, established during the Tudor period of the Kingdom of Ireland in 1552. The Ulster King of Arms' duties in relation to Northern Ireland were taken over by the Norroy and Ulster King of Arms.

As of 2026, a notice on the website of the Office of the Chief Herald stated that the office is "currently not accepting any new applications for grants or confirmations of arms [...or...] in a position to answer general queries about heraldry".
