How many episodes does House M.D. have in total?

House M.D. has 177 episodes in total.

Fox broadcast those 177 episodes across eight seasons from 2004 to 2012. The total includes the show's regular installments and reflects the complete television run rather than a single season's episode count. Most episodes center on a patient with an unusual or initially unexplained illness.

The series uses a recurring diagnostic structure, but its episode total includes substantial variation in story format. Some installments focus heavily on House's personal life, his relationships with colleagues, or institutional problems at Princeton-Plainsboro. The number therefore describes the whole series, not just the medical-case episodes.

A common mix-up is to confuse 177 episodes with eight seasons or with the number of episodes in a particular season. Season lengths vary, so multiplying a standard season length does not produce the official total. The canonical series count is 177 episodes.
