How many seasons did House M.D. have?

House M.D. had eight seasons.

The medical drama premiered on Fox in November 2004 and concluded in May 2012. Across its eight-season run, the series followed Gregory House and several different diagnostic teams at Princeton-Plainsboro Teaching Hospital.

The team changed repeatedly as characters left, returned, or moved into different hospital roles. Despite those changes, the show retained its central focus on difficult diagnoses and House’s unconventional methods. The final season introduced new developments in House’s personal and professional life before the series ended.

A common counting mistake is to treat major team changes as separate series phases rather than seasons. House M.D. remained one continuous series, with eight numbered seasons. Its conclusion was a planned series finale, not a cancellation announced after an incomplete season.
