In House M.D., Dr. House’s father is named John House.
John House is introduced through the show’s exploration of Gregory House’s childhood and family relationships. House believed John was his biological father, but the series later reveals that his mother had an affair, creating uncertainty about House’s biological parentage. The revelation adds another layer to House’s distrust of authority and family narratives.
John is portrayed as a strict Marine Corps pilot and minister in accounts of House’s upbringing. The character is associated with discipline and moral expectations, traits that contrast with Gregory’s rebellious adult behavior. House’s memories of his father help explain parts of his personality without reducing the character to a single cause.
The name is easy to confuse with House’s own first name, Gregory, or with James Wilson, his adult friend. John House is specifically the name used for the man House regarded as his father during childhood.
