In House M.D., what is the name of the fictional hospital where Gregory House practices medicine?

In House M.D., Gregory House practices medicine at Princeton-Plainsboro Teaching Hospital.

Princeton-Plainsboro is a fictional teaching hospital in New Jersey and the primary setting for the series. Its name combines references to real communities in central New Jersey, including Princeton and Plainsboro, helping the hospital feel geographically plausible while remaining fictional.

The hospital supports the show's diagnostic cases, emergency care, surgery, oncology, intensive care, and research storylines. House leads a specialized diagnostic medicine team there, while other recurring characters work in departments such as oncology, neurology, cardiology, and hospital administration.

Viewers sometimes confuse Princeton-Plainsboro with a real hospital or with Princeton University facilities. The series uses the fictional institution to give writers freedom over its departments, staff, policies, and cases. Princeton-Plainsboro is therefore a setting created for the drama, not the name of a real New Jersey teaching hospital.
