Which fictional detective is a major inspiration for Dr. House in House M.D.?

Sherlock Holmes is a major inspiration for Dr. Gregory House in House M.D. The series adapts Holmesian detective ideas to medicine, making diagnosis the equivalent of solving a difficult case.

The parallels appear in several details. House and Holmes rely on observation and deduction, have a close companion in Wilson and Watson, and use unconventional methods to reach conclusions. House’s surname also recalls Holmes’s name, while Wilson’s surname echoes Dr. John Watson.

Both characters are highly intelligent, socially difficult, and willing to challenge ordinary procedures. House’s dependence on Vicodin is another adaptation of Holmes’s association with drug use in some Arthur Conan Doyle stories, though the medical drama develops its own storyline around addiction and pain.

House M.D. is not a direct retelling of a Holmes story. It uses the detective framework as a creative foundation for original medical cases, hospital relationships, and ethical conflicts.
