The North Infirmary (Irish: Otharlann Chorcaí Thuaidh) was the first general hospital to be opened in Cork.

The North Infirmary was built on the site of the St Mary’s Church that was destroyed during the Siege of Cork in 1690.

[3] In 1883 construction began on a new north wing with funds donated by Lady Combermere, daughter of Dr Gibbings, a physician at the infirmary.

[2] By the time Sr Teresa died in 1909, the infirmary had increased its capacity to 115 beds; it contained a modern operating room, spacious wards and highly trained nurses.

In 1917 the infirmary was used by military authorities to treat wounded soldiers sent home from the front lines during the First World War.
