The television series House, M.D. broadcast 177 episodes across eight seasons. The episode count includes the regular installments that followed Gregory House from the 2004 premiere through the 2012 finale.
The series used a case-of-the-week structure, but its episodes also developed long-running stories about House’s addiction, friendships, hospital leadership, and diagnostic colleagues. This combination made the total larger than a short-form medical miniseries while keeping the show centered on difficult diagnoses.
The episode list is organized by season and includes titles, directors, writers, original air dates, and U.S. viewership information. The final broadcast episode was “Everybody Dies,” which aired on May 21, 2012.
Counts can vary when viewers include unaired material, international edits, web extras, or special broadcasts. The standard English-language series total is 177 broadcast episodes. The number does not mean 177 separate medical diagnoses, because some episodes emphasize character stories, hospital disputes, or continuing plots rather than a wholly independent case.
