What is the name of the fictional hospital where House M.D.’s main characters work?

The fictional hospital where the main characters work in House M.D. is Princeton-Plainsboro Teaching Hospital.

The institution is located in Princeton, New Jersey, and serves as the principal setting for nearly the entire series. Gregory House heads its Department of Diagnostic Medicine, a fictional specialty devoted to solving unusually complex cases that other doctors have been unable to diagnose.

Although Princeton-Plainsboro is fictional, the show gives it the structure of a major teaching hospital, including emergency, surgical, oncology, neurology, and intensive-care departments. Its teaching-hospital identity also explains why House works with rotating teams of younger doctors and why medical education is woven into the cases.

Viewers sometimes shorten the name to “Princeton-Plainsboro” or confuse it with a real New Jersey institution. The hospital’s name combines Princeton, the town associated with the setting, and Plainsboro, a nearby township. The series uses the hospital as both a workplace and a recurring dramatic environment for its medical mysteries.
