House M.D. produced 177 episodes.
Those episodes were broadcast across eight seasons from 2004 to 2012. Most used the series’ familiar structure: a patient arrived with puzzling symptoms, House’s team proposed competing diagnoses, tests eliminated possibilities, and a final explanation emerged—often after a misleading early assumption.
The episode total includes the pilot and the series finale, “Everybody Dies.” It also includes episodes with unusual formats, such as “Three Stories,” which uses multiple patient narratives to explore House’s past and his medical reasoning.
Episode counts can vary in casual lists because some outlets package two-hour finales as separate broadcasts or combine them as single events. The standard series count for House M.D. is 177 episodes, a figure associated with its eight-season run and its regular broadcast installments.
