House M.D. had 177 episodes across its eight-season run.
The episode total includes the regular broadcast episodes from the series’ premiere in 2004 through its finale in 2012. Episodes generally follow House and his colleagues as they investigate a patient whose symptoms resist ordinary diagnosis, while continuing personal and institutional storylines.
The count is easy to confuse with the number of seasons, which was eight, or with the number of episodes in an individual season. Season lengths were not identical, and some installments were structured as major two-part stories or special narrative experiments. The total listed for the series remains 177 episodes.
The final episode, “Everybody Dies,” was broadcast on May 21, 2012. It concluded the fictional story rather than adding a separate ninth-season installment. Episode guides may list production details, original air dates, and titles separately, but they agree on the series total of 177 regular episodes.
