House M.D. produced 177 episodes across its original eight-season run.
The series aired from November 16, 2004, to May 21, 2012. Those episodes followed House and several generations of diagnostic fellows, while recurring characters and hospital politics developed over time. The count refers to the regular scripted episodes of the American television series.
Episode totals can be confused with season counts, broadcast repeats, or differently packaged international listings. The eighth season was the final season, and its conclusion brought the complete original run to 177 episodes. The number is therefore a series-production total, not the number of episodes aired in one season or the number of episodes featuring one particular medical team.
