Children's Health Ireland (CHI; Irish: Sláinte Leanaí Éireann, SLÉ) is a statutory body established in 2018 to oversee the development and governance of specialist acute paediatric hospital services in Ireland.^[1] The name "Phoenix Children's Health" had originally been announced for this entity in 2017,^[2] but that name was abandoned following legal action from Phoenix Children's Hospital.

On 1 January 2019, CHI took over governance of the three tertiary children's hospitals in Dublin (Our Lady's Children's Hospital, Crumlin, Temple Street Children's University Hospital, and the National Children's Hospital).^[1] In doing so, it succeeded the Children's Hospital Group, which had previously been formed in August 2013 with a view to integrating these three separate hospitals under a single board of management.

The three hospitals will eventually transfer their operations to the new children's hospital, an as-yet unnamed tertiary children's hospital that is currently under construction on the campus of St. James's Hospital in Dublin.

Other planned CHI centres include:

• Children's Health Ireland at Connolly, an outpatients' and urgent care centre (colocated with Connolly Hospital)
• Children's Health Ireland at Tallaght, an outpatients' and urgent care centre (colocated with Tallaght University Hospital)

The name will be extended outside of Dublin throughout Ireland on a phased basis.^[2]
