National Children's Hospital Ireland

National Children's Hospital Ireland (NCHI; Irish: Ospidéal Náisiúnta Leanaí Éireann) is a children's hospital under construction in Dublin, Ireland, as a regional secondary and national tertiary centre. Referred to throughout most of the project simply as the new children's hospital, it was given its name in June 2025.

The new hospital, on the same campus as the existing St. James's Hospital, will combine the services previously provided at Dublin's three tertiary children's hospitals: Children's Health Ireland at Crumlin (formerly Our Lady's Children's Hospital); Children's Health Ireland at Temple Street (formerly Temple Street Children's University Hospital); and Children's Health Ireland at Tallaght (formerly the National Children's Hospital at Tallaght University Hospital).

NCHI is planned to be the lead centre in the Children's Health Ireland network, which is proposed to encompass all acute paediatric services in Ireland. In addition to the main hospital at St James's, satellite centres are expected to operate attached to Tallaght Hospital and Connolly Hospital providing local urgent care and outpatient services.
