House M.D. broadcast 177 episodes across its eight-season run.
The series began in 2004 and concluded in 2012. Its episodes generally combined a central medical mystery with ongoing stories about Gregory House, his colleagues, and the changing diagnostic teams at Princeton-Plainsboro Teaching Hospital.
The total includes the series’ regular broadcast episodes over all eight seasons. It does not mean the show had 177 seasons or that every international release necessarily followed the same scheduling pattern. Specials, previews, and reruns are also separate from the official episode count.
Episode counts can vary in informal listings when recap programs, unaired pilots, or bonus material are included. The standard count associated with the television series is 177 episodes. The final installment, “Everybody Dies,” brought the main run to a close in May 2012.
