The final regular episode number of House M.D. was 177.
The series produced 177 episodes across eight seasons from 2004 to 2012. Its last regular installment was “Everybody Dies,” which aired on May 21, 2012. The program’s episode count reflects the long broadcast seasons typical of network television dramas during that period.
House M.D. also had a retrospective special titled “Swan Song.” Because that program aired after the dramatic finale and revisited the series’ history, episode-count discussions can differ depending on whether a source counts only scripted regular episodes or includes the special in a broader broadcast total.
The number is also sometimes confused with the number of episodes in a particular season. Season lengths varied, and the eighth season had 22 episodes. Counting the complete scripted run, however, gives 177 episodes. The total includes the pilot and the finale but does not turn the retrospective special into a regular story episode.
