House M.D. produced 177 episodes across its full television run.
The series aired on Fox for eight seasons, from 2004 to 2012. Those episodes combine self-contained diagnostic mysteries with continuing stories about House, his colleagues, hospital politics, and changing medical teams. Most seasons were built around a regular broadcast schedule, although episode totals varied.
The count includes the series’ regular episodes across all eight seasons. It does not mean that every episode has the same format or length: some installments focus more heavily on a patient case, while others emphasize character events or unusual narrative structures. The final season brought the total to 177.
Episode totals are often confused with the number of seasons, which was eight, or with the number of episodes in a particular season. Another possible source of confusion is international scheduling, since broadcasters sometimes split or reorder seasons. The standard series total cited for House M.D. is 177 episodes.
