The TV series House M.D. produced 177 episodes.
Those episodes were broadcast across eight seasons on Fox between November 2004 and May 2012. The program used a case-of-the-week structure, but its continuing storylines followed House, his diagnostic colleagues, hospital administrators, and patients whose conditions affected the doctors personally.
The episode total includes the regular narrative installments of the series. It does not mean that every season had the same number of episodes. Network scheduling, production decisions, and the show's final season all affected the distribution across seasons.
The number is also distinct from the count of episodes in which a particular actor appeared or from the number of episodes focused on one diagnostic team. Cast membership changed over time, especially after major character departures and team reorganizations. Counting the complete series gives the standard total of 177 episodes.
