At which fictional hospital does House lead his diagnostic team in House M.D.?

House leads his diagnostic team at the fictional Princeton-Plainsboro Teaching Hospital in House M.D. The hospital is the main setting for the series and the place where most diagnostic mysteries unfold.

Princeton-Plainsboro is presented as a teaching hospital in New Jersey. Its name combines the real communities of Princeton and Plainsboro, creating a plausible institutional setting while allowing the writers broad fictional freedom.

The hospital provides several recurring locations, including the diagnostics department, clinic, offices, operating areas, and patient rooms. Other major characters work there, including James Wilson, Lisa Cuddy, and the members of House's changing diagnostic teams.

The show was filmed primarily in and around Los Angeles, rather than at a real Princeton-area hospital. The exterior used for the fictional hospital was filmed at the campus of Princeton University, while many interior scenes were shot on studio sets.
