The Adelaide Hospital (named after Adelaide, wife of William IV) was a general and teaching hospital in Dublin, Ireland until it became part of the new Tallaght Hospital in 1998.
The hospital was founded in 1839 by Dr. Albert Jasper Walsh (1815–1880) when he was just 26 years old, and was originally intended only for Protestant patients. The well-known John T. Kirby and Maurice Colles were honorary surgeons. Its first premises was at 43 Bride Street and it continued there until 1846. It was then closed for a time and after refunding re-opened in Peter Street in 1858, close to two existing schools of medicine. One of these, the Ledwich School, was incorporated into the hospital in 1894.
The Adelaide hospital was a general teaching hospital for many years and in the forefront of medical advances. Its charter, which dates from 1920, was one of the last royal charters granted in Ireland.
When the Irish Hospitals' Sweepstake was set up in 1930 to finance hospitals, the Adelaide was the only hospital at the time not to accept money from the Hospitals Trust, as the governors disapproved of sweepstakes.
After its incorporation with the Meath Hospital and the National Children's Hospital the Adelaide became part of the new Tallaght Hospital in June 1998. The former hospital building in Peter Street has been converted into apartments.
