House M.D. ran for 177 episodes across eight seasons.
The series began on Fox in November 2004 and concluded in May 2012. Its episode count includes the regular installments broadcast during those eight seasons, covering House’s diagnostic cases, hospital politics, changing medical teams, and long-running personal storylines.
The total is sometimes confused with the number of episodes in other long-running medical dramas, or with the number of episodes in House’s first several seasons alone. House M.D. had a changing schedule and occasional two-part or special-format stories, which can make informal episode counts look different. The accepted series total is 177.
The episode count also reflects the show’s evolution. House’s original diagnostic team changed over time, while characters such as Wilson and Cuddy remained central to the broader story. The final episode, “Everybody Dies,” brought the eight-season run to its conclusion.
