The hospital, which was initially established as a tuberculosis sanitarium, was designed by Norman White and constructed by Sisk Builders.
It was named in memory of the Irish republican leader, James Connolly, and officially opened as the James Connolly Memorial Hospital in 1955.
Following the introduction of effective antibiotic treatment, the hospital was re-designated as a general hospital for the North West area of Dublin and re-opened as such in 1973.

In 2005 a new accident and emergency unit, new operating theatres, new surgery facilities and a new intensive care unit were officially opened by the Minister of State for Children, Brian Lenihan, who also announced that the hospital would be renamed the Connolly Hospital Blanchardstown.

A satellite facility for the National Children's Hospital, providing outpatient facilities and an urgent care centre is due to open in summer 2019.
