The Mater Misericordiae University Hospital (commonly known as the Mater) is a major teaching hospital, based at Eccles Street, Phibsboro, on the northside of Dublin, Ireland. Mater misericordiae means "Mother of Mercy" in Latin, a title of the Blessed Virgin Mary from the Catholic hymn Salve Regina and alludes to its founders, the Sisters of Mercy.

The hospital stands next to the Children's University Hospital, Temple Street, and has provided public hospital care to adult patients for more than 150 years. It was established by the Sisters of Mercy as a Roman Catholic voluntary hospital within the health system of Ireland.

It is associated with the National University of Ireland (University College Dublin School of Medicine) and provides national tertiary care in many branches of medicine.

The first endoscope was used in the Mater. The hospital is mentioned by Buck Mulligan in James Joyce's Ulysses.
