The television series House, M.D. produced 177 episodes across its original run.
Those episodes were broadcast over eight seasons from 2004 to 2012. Most follow a medical-mystery structure in which House and his team investigate a difficult or unusual case, while continuing storylines develop around the hospital staff and House’s personal life.
The episode total includes regular installments from all eight seasons and the two-part series finale presentation is counted as two episodes in standard episode lists. Episode counts can therefore differ if a guide combines multipart stories or treats a broadcast event as a single entry.
The figure is also distinct from the number of patients, diagnoses, or cases depicted in the series. Many episodes include multiple diagnostic possibilities before the team reaches its final explanation. Standard television references and episode guides list House, M.D. at 177 episodes in total.
