House M.D. broadcast 177 episodes during its full eight-season run.
The series premiered on Fox in November 2004 and concluded in May 2012. Its 177-episode total includes the regular episodes produced across all eight seasons, from the opening story “Everybody Lies” to the finale “Everybody Dies.”
Episode totals can vary in casual discussions because two-hour broadcasts may be counted differently by viewers, and some international listings split or combine specials. Standard series references list House as having 177 episodes. The total is therefore different from the number of seasons and from the number of episodes in any individual season.
The large episode count reflects the show’s long network run and its continuing ensemble changes. Over time, the diagnostic fellows and hospital leadership changed, but the series retained House’s central role and its case-of-the-week medical mystery format.
