The television series House, M.D. has 177 episodes.
Those episodes were broadcast across eight seasons from 2004 to 2012. Most installments center on a puzzling patient case, while continuing storylines follow House, his diagnostic teams, hospital leadership, friendships, and personal struggles.
The total counts the regular episodes of the series, including its two-part stories as separate broadcast episodes when listed individually. It does not mean that the show had 177 seasons, nor does it refer only to episodes focused on House’s original team.
The series finale, “Everybody Dies,” aired in 2012. Episode totals can differ in informal listings if specials, recap programs, international edits, or two-part broadcasts are grouped differently, so an episode guide is the clearest reference for the standard count.
