In House M.D., what is the name of the fictional hospital where Dr. House leads the Diagnostic Medicine department?

In House M.D., Dr. House leads the Diagnostic Medicine department at Princeton-Plainsboro Teaching Hospital.

The hospital is a fictional teaching hospital in New Jersey and serves as the main setting for the series. Its name combines the real New Jersey communities of Princeton and Plainsboro, helping establish the show's regional setting without using an actual hospital as the primary location.

Princeton-Plainsboro is portrayed as a large academic medical center with specialist departments, intensive-care facilities, laboratories, and a teaching mission. Many episodes move beyond House's department, showing its emergency room, clinic, operating rooms, and administrative offices.

Viewers sometimes shorten the name to “Princeton-Plainsboro” or simply “the hospital.” It should not be confused with the fictional hospitals from other medical dramas, such as Seattle Grace or Sacred Heart.
