The complete TV series House M.D. contains 177 episodes. Those episodes were broadcast across eight seasons from November 2004 through May 2012.
The episode total includes the regular installments that follow House's diagnostic cases, hospital politics, and personal relationships. Most episodes use a case-of-the-week structure, but continuing storylines connect the seasons and develop the doctors beyond their medical puzzles. The show also produced two-part stories and episodes with unusual narrative formats, which can make simple episode counts appear inconsistent across listings.
House M.D. is often described as an eight-season series, but eight is its season count rather than its episode count. The number 177 refers to the complete broadcast run, including the series finale, “Everybody Dies.” Some databases may organize specials or extended episodes differently, so the standard series total is the canonical figure used in reference summaries.
