House M.D. is chiefly modeled on which famous fictional detective?

House M.D. is chiefly modeled on Sherlock Holmes.

Gregory House shares several traits with Arthur Conan Doyle’s detective: extraordinary powers of deduction, contempt for routine thinking, a preference for solving puzzles, and a difficult personality that can isolate him from others. The medical cases function like mysteries, with symptoms serving as clues.

The connection appears in names and story details as well. House and Holmes have similar surnames, and House’s apartment number is 221B, echoing Holmes’s famous address at 221B Baker Street. House’s reliance on a cane also parallels Holmes’s use of a violin and other characteristic details in the broader adaptation concept, though the characters remain distinct.

House is not a direct retelling of a Holmes story. It transfers the detective’s method into diagnostic medicine, making the patient’s illness the mystery and the physician the investigator.
