The television series House M.D. has 177 episodes.
Those episodes were broadcast across eight seasons on Fox from November 2004 through May 2012. Most episodes combine a central diagnostic mystery with continuing stories about Gregory House, his colleagues, and the administration of Princeton-Plainsboro Teaching Hospital.
The count includes the complete regular series, not a separate television film or a collection of unaired pilots. Episode totals can appear different in some listings because international broadcasters may divide or package episodes differently, but the standard series count is 177.
The program’s final episode, “Everybody Dies,” brought the main story to a close on May 21, 2012. Counting episodes is distinct from counting seasons: the show had eight seasons, and several seasons contained more than 20 installments.
