House M.D. produced 177 episodes across its eight seasons.
The medical drama premiered in 2004 and concluded in 2012. Its episode total includes the regular broadcast stories released during the complete series run, from the pilot through the finale. Most episodes follow a patient mystery that moves through differential diagnoses, tests, treatment changes, and a final explanation, while longer arcs develop the doctors’ personal lives.
The total is distinct from the number of seasons: the program had eight seasons, but each season contained many individual episodes. It is also separate from the number of episodes broadcast in a particular country, because international schedules and editing practices could vary.
Episode counts are useful when comparing House M.D. with other long-running scripted dramas. The series’ 177-episode run gave its recurring doctors room to change departments, leave and return, and face storylines that extended beyond individual cases. The official episode list is the clearest reference for the complete count.
