House M.D.'s Gregory House was partly inspired by which fictional detective?

Gregory House in House M.D. was partly inspired by the fictional detective Sherlock Holmes.

The connection appears in several details: both characters rely on unusually sharp observation and deduction, both are portrayed as difficult personalities, and both solve cases that baffle other professionals. House's surname also resembles “Holmes” in its connection to a residence, while Wilson's name recalls Dr. John Watson, Holmes's friend and companion.

The series adapts detective-story structure to medicine. Each episode typically presents a mysterious illness, introduces misleading evidence, and follows House's team as it tests competing explanations. The diagnosis functions like the solution to a mystery.

House M.D. is not a direct adaptation of a Sherlock Holmes story. Instead, it uses Holmesian ideas in a contemporary hospital drama. This is why the character is often described as a medical counterpart or loose analogue of Holmes rather than as Holmes himself.
