What is the full name of the doctor known as Dr. House in House M.D.?

The doctor known as Dr. House in House M.D. is Gregory House.

Gregory House is the series’ central character and the head of diagnostic medicine at Princeton-Plainsboro Teaching Hospital. He is portrayed as exceptionally intelligent, observant, and inventive, but also abrasive, secretive, and frequently unwilling to follow hospital rules.

The character’s surname and personality deliberately evoke Sherlock Holmes. House investigates medical mysteries much as Holmes investigates crimes, relying on clues, deduction, and a willingness to challenge assumptions. The connection is also reflected in House’s friendship with James Wilson, whose role parallels Holmes’s companion in broad structural terms.

House’s first name is Gregory, not George or another common variation. Hugh Laurie played him throughout the series. His chronic leg pain, cane, Vicodin dependence, and difficult relationships are major parts of the character, but the defining professional trait is his ability to diagnose rare or complicated illnesses.
