House M.D. produced 177 episodes across its complete eight-season run.
The total includes the regular scripted episodes broadcast from 2004 through 2012. Across those episodes, the series followed Gregory House and changing teams of physicians as they investigated unusual symptoms, rare diseases, and difficult ethical problems at Princeton-Plainsboro Teaching Hospital.
The episode count is separate from the number of seasons: the show had eight seasons, with episodes distributed unevenly across them. It is also separate from retrospective programming such as “Swan Song,” which was associated with the series’ conclusion but is not counted as an additional scripted story episode in the same way.
Episode totals can vary in casual references when specials, recaps, or regional broadcast listings are included. The standard series figure for House M.D.’s regular run is 177 episodes, ending with “Everybody Dies.”
