How many episodes of House M.D. were broadcast across its original run?

House M.D. broadcast 177 episodes across its original eight-season run. The series aired on Fox from November 16, 2004, until May 21, 2012.

Most episodes use a case-of-the-week structure: House and his colleagues investigate a patient with unexplained symptoms, test competing diagnoses, and revise their conclusions as new evidence appears. Longer character arcs run alongside those medical stories, including House's addiction, team changes, and relationships with Wilson and Cuddy.

The episode total includes the two-part episodes counted as separate installments in the series' broadcast episode list. This is why episode counts can sometimes look different in guides that group a two-part story under one title. The commonly cited broadcast total for the complete series is 177.
