What is the full name of the fictional hospital in House M.D.?

The fictional hospital in House M.D. is Princeton-Plainsboro Teaching Hospital.

The hospital provides the main setting for the series and houses House's diagnostic team, the emergency department, operating rooms, intensive-care facilities, and administrative offices. Its name combines the real-world Princeton and Plainsboro areas of New Jersey.

Although the hospital is fictional, the series used recognizable New Jersey locations and medical terminology to give it a realistic appearance. The exterior commonly associated with Princeton-Plainsboro was filmed at Princeton University’s Frist Campus Center, while other locations represented different parts of the hospital.

The institution is often shortened to PPTH by characters and fans. That abbreviation can cause confusion with real hospitals, but Princeton-Plainsboro Teaching Hospital exists only within the show's fictional universe.
