Which character’s name gives House M.D. its Sherlock Holmes-inspired surname?

Gregory House is the character whose surname reflects House M.D.’s Sherlock Holmes inspiration.

The character’s surname resembles “Holmes,” and both figures are brilliant investigators known for deduction, unconventional methods, and difficult personalities. House’s friend James Wilson fills a role that parallels Dr. John Watson in several aspects of the relationship.

The connection goes beyond the name. House often solves cases by noticing details others overlook, rejects routine explanations, and uses provocative behavior to expose hidden truths. Some episodes also adapt Holmes-related plot ideas in medical form.

House is not a direct modern version of Holmes in every detail. The series combines detective-story structure with hospital medicine, and House’s addiction, disability, and professional conflicts create a distinct television character.
