House M.D. produced 177 episodes across its entire eight-season run.
The series aired on Fox from 2004 to 2012 and used a case-of-the-week structure supported by continuing character storylines. Most episodes centered on a patient with an unusual or difficult-to-explain illness, while House’s relationships and personal decisions developed across the season.
The total includes the two-part series finale, “Everybody Dies,” which is counted as two episodes in many episode listings. That detail can cause minor differences when viewers count story installments rather than official episode numbers.
The episode count is also distinct from the number of seasons: House had eight seasons but 177 individual broadcast episodes. Episode guides list them by season and production order, and the series finale was broadcast on May 21, 2012.
