House M.D. ended after 177 episodes.
The series ran for eight seasons on Fox, beginning with its 2004 premiere and ending with the 2012 finale. The episode total includes the regular broadcast episodes across all seasons and reflects the program’s long run as a major American medical drama.
Episode counts can be confusing because some stories were broadcast as two-part episodes, while others were extended or treated as special event installments. Season totals also varied, so adding the seasons requires using the official episode listings rather than assuming an identical number every year.
The final episode was “Everybody Dies,” which aired on May 21, 2012. The total is not the number of medical cases House investigated, the number of doctors who served on his teams, or the number of episodes in a single season. It is the complete series count, including the pilot and the eighth-season conclusion.
