The New New York Hospital was a hospital near to the city of New New York run by the Sisters of Plenitude. It was clearly identifiable by its white structure and the green crescents on the structure.

The Hospital included areas for surgery, post-op and nano-dentistry and had a secret intensive care unit where the Flesh were kept for experimentation. There was also a Pleasure Gardens area which required identification cards to access; cuttings from the Gardens was forbidden. The lifts in the Hospital were voice-activated, and visitors underwent an automatic three-stage disinfection process while traveling between floors.

When the Flesh were discovered in the year 5,000,000,023, the Hospital was closed down and the Sisters of Plenitude was dissolved by the New New York Police Department.

The Tenth Doctor complained of the fact that unlike other hospitals, this particular one didn't have a little shop.

The staff of the Hospital included Matron Casp, Sister Jatt and Novice Hame. The Sisterhood's motto was "Hope, harmony, and health", which was broadcast on the building's PA system at regular intervals.

The patients of the Hospital included the Face of Boe, the Duke of Manhattan, an unnamed patient and a number of new humans. One of the more luxurious wards was Ward 26, where ambient temperatures were kept at fourteen degrees cohezic to promote an atmosphere of healing and well-being.
