House M.D. has 177 episodes across its eight seasons. The total covers the scripted episodes broadcast by Fox from the 2004 premiere through the 2012 series finale.
The episode count reflects a conventional network television schedule, with several seasons containing more than 20 episodes. Each episode usually combines a medical puzzle with character conflicts, allowing the series to develop both its diagnostic cases and its long-running relationships.
The show’s title is sometimes listed as House, M.D. or simply House, which can create confusion when comparing episode guides. The count also excludes retrospective programming such as “Swan Song,” because that material is categorized separately from the scripted episode run.
The 177-episode total is associated with the main American television series. International broadcasts may divide seasons differently or schedule episodes in another order, but they do not change the canonical number of episodes produced for the series.
