The complete House M.D. television series contains 177 episodes.
Those episodes were broadcast across eight seasons from 2004 to 2012. The series follows Gregory House and successive diagnostic teams as they investigate complex medical cases, while continuing storylines track relationships, careers, addiction, and hospital politics.
Episode totals can seem inconsistent because television listings sometimes distinguish regular episodes from specials, recap programs, or unaired material. The standard episode count for the main House M.D. series is 177, arranged in the show’s eight numbered seasons.
The total is also easy to confuse with the number of years the program was on air. Since the premiere occurred in November 2004 and the finale aired in May 2012, the broadcast run touched parts of nine calendar years, but that does not make nine seasons. The definitive count remains 177 episodes.
