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

The story behind the answer

The fictional doctor known as House in House M.D. is Gregory House. He is the series’ central character and leads the Department of Diagnostic Medicine at Princeton-Plainsboro Teaching Hospital.

House is portrayed as a medical genius who specializes in solving unusual cases that have resisted ordinary diagnosis. He often uses differential diagnosis, intensive testing, and unconventional reasoning. His approach is effective but frequently creates ethical, legal, and professional problems.

The character’s full name is Gregory House, and his surname deliberately recalls Sherlock Holmes. The connection extends beyond the name: House lives at 221B Baker Street in one storyline, plays guitar and piano like Holmes plays violin, and has a close friend whose role parallels Dr. Watson.

House also has a chronic leg injury that causes severe pain and contributes to his dependence on Vicodin. Hugh Laurie played the character for all eight seasons. The character’s name is sometimes shortened in dialogue to “House,” but Gregory House is the canonical full name.
