What is the first name of the title doctor in House M.D.?

The title doctor in House M.D. is named Gregory House.

Gregory House is the central fictional character of the series, portrayed by Hugh Laurie. He leads a specialized diagnostic team and is known for solving complicated cases through unconventional reasoning, often while clashing with patients, colleagues, and hospital administrators.

House's given name is occasionally overshadowed by the character's surname, which is used constantly in the hospital. His full name also helps distinguish him from the show's title, which refers to the character and not to a real medical institution.

The character was partly inspired by Sherlock Holmes. Both figures are exceptionally observant investigators, use deductive reasoning, and have a close friend who helps interpret their behavior. House's chronic leg pain and reliance on Vicodin are distinctive elements of the television character.
