In House M.D., what is the fictional New Jersey hospital where Gregory House leads the diagnostic medicine team?

In House M.D., Gregory House leads the diagnostic medicine team at the fictional Princeton-Plainsboro Teaching Hospital.

The hospital is located in Princeton, New Jersey, and serves as the principal setting for nearly the entire series. Its diagnostic medicine department handles unusual or unexplained cases that other doctors have been unable to solve. House and his rotating team investigate symptoms, review medical histories, and frequently revise their diagnoses as new evidence appears.

Princeton-Plainsboro is fictional, although the series uses recognizable medical and New Jersey details to make the setting feel realistic. The show was filmed mainly in California, with the hospital exterior represented by a building on the Universal Studios backlot. The name is sometimes shortened by viewers to “Princeton-Plainsboro” or simply “the hospital,” but the full fictional name includes “Teaching Hospital.”

The hospital’s teaching status also explains why medical students, fellows, residents, and specialists regularly appear in its cases. Its fictional location should not be confused with Princeton University or a real hospital bearing the same name.
