House M.D. produced 177 episodes in total.
The series ran for eight seasons, from its 2004 premiere through its 2012 finale. The episode total includes regular one-hour installments, two-part stories counted as separate episodes, and the complete final season. “Everybody Dies,” broadcast on May 21, 2012, is episode 177 overall.
Episode counts can vary in casual references because some broadcasts or streaming services present two-part stories differently. For example, a two-part narrative may be promoted as one event while official episode numbering treats its chapters separately. The standard series total used in reference sources is 177.
The number is also distinct from the count of episodes directed or written by any one contributor. Hugh Laurie directed two episodes, while the series employed a large writing and directing staff over its eight-season run.
