In which U.S. state is Princeton-Plainsboro located in House M.D.?

Princeton-Plainsboro is located in New Jersey in House M.D. The fictional teaching hospital is positioned in the Princeton area, linking the series to a recognizable part of the northeastern United States.

The New Jersey setting helps explain the show’s visual and cultural environment. Princeton and Plainsboro are both real New Jersey place names, although Princeton-Plainsboro Teaching Hospital is invented for the series. The location also places the hospital within reach of New York City and Philadelphia, major metropolitan areas that fit the show’s large referral-hospital premise.

The series was filmed primarily in Los Angeles, California, despite its New Jersey setting. The exterior of the fictional hospital was represented by Princeton University’s Frist Campus Center, which helped create the impression of an East Coast academic institution.

The state should not be confused with Pennsylvania, even though Philadelphia is nearby and appears in the wider regional geography. Princeton itself is in New Jersey, and that is the state assigned to the hospital in the series.
