In House M.D., what is the first name of Dr. House?

In House M.D., Dr. House’s first name is Gregory.

The character’s full name is Dr. Gregory House, and he is the central figure of the medical drama. Hugh Laurie played House throughout the series, portraying him as a highly intelligent but abrasive diagnostician who leads a team solving unusually difficult cases.

The character’s name deliberately echoes Sherlock Holmes. Both figures are famous for deductive reasoning, live at a numbered address, and have a close friend whose name resembles Watson: Dr. James Wilson in House M.D. House’s surname also inspired the title of the series.

Viewers sometimes use “House” as though it were the character’s first name, but it is his surname. “Gregory” is the distinctive canonical first name used in the show and in official character references.
