The original House M.D. series produced 177 regular episodes.
Those episodes were broadcast across eight seasons on Fox between 2004 and 2012. The total counts the standard narrative episodes of the series, rather than unaired material, promotional specials, or unrelated television appearances by the cast.
Most episodes follow a recognizable diagnostic structure: a patient presents with puzzling symptoms, House’s team proposes competing explanations, tests eliminate possibilities, and a final diagnosis emerges. The formula supports both medical suspense and continuing stories about House, Wilson, Cuddy, and the doctors on the diagnostic team.
The number is sometimes confused with the show’s season count or with totals from international scheduling packages. The reliable series total is 177 episodes, while the final episode was “Everybody Dies,” broadcast in May 2012.
