What is Gregory House’s first name in House M.D.?

Gregory is the first name of the title character in House M.D.

The character is formally known as Dr. Gregory House, and Hugh Laurie portrays him throughout the series. His surname and deductive style deliberately evoke Sherlock Holmes, whose first name is also associated with a famous fictional detective.

House works as a diagnostician at Princeton-Plainsboro Teaching Hospital. He is known for solving complex cases, challenging conventional medical thinking, and using a cane after a serious leg injury. His first name appears in professional records, dialogue, and the character’s full name.

The answer is not “James,” even though James Wilson is House’s closest friend and colleague. “Robert” belongs to Robert Chase, another doctor on the diagnostic team. Those nearby names account for some confusion when the characters are discussed together.
