The Hospital and Free School of King Charles II, Oxmantown, also called The King's Hospital (KH; Irish: Scoil Ospidéal an Rí[1]) is a Church of Ireland co-educational independent day and boarding school situated in Palmerstown, County Dublin, Ireland.

It is on an 80-acre campus beside the River Liffey, called Brooklawn, named after the country houses situated on the site and in which the headmaster and his family reside.

[8] From 1783 to 1971, the school was located in Blackhall Place, Dublin, later the headquarters of the Law Society of Ireland in a building and amongst a street plan that was designed by the architect Thomas Ivory and encompassed much of what was previously the land of Oxmantown Green.

[10] Entitled "Fragment From An Unpublished Dialogue Of Galileo", it was written for the school's 1955 edition of the annual Blue Coat magazine to coincide with Schrödinger leaving Dublin to take up his appointment as Chair of Physics at the University of Vienna.

It is now in the possession of King's Hospital alumnus Professor Jonathan Coleman in CRANN at Trinity College Dublin.

The school has teams for rugby, hockey, cricket, athletics, cross-country, badminton, soccer, basketball and swimming.
