Ordnance Survey Ireland (OSI; Irish: Suirbhéireacht Ordanáis Éireann) was the national mapping agency of the Republic of Ireland. It was established on 4 March 2002 as a body corporate.[1] It was the successor to the former Ordnance Survey of Ireland. It and the Ordnance Survey of Northern Ireland (OSNI) were themselves the successors to the Irish operations of the British Ordnance Survey. OSI was part of the Irish public service. OSI was headquartered at Mountjoy House in the Phoenix Park in Dublin, which had previously been the headquarters of the British Ordnance Survey in Ireland until 1922.

In March 2023, the Ordnance Survey was dissolved and its functions transferred to a new body called Tailte Éireann, which also incorporates the Property Registration Authority and the Valuation Office.[2]
