What is the full name of the main doctor in House M.D.?

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

Dr. Gregory House is the show's central character, a medical diagnostician known for solving unusually difficult cases. He leads a team at the fictional Princeton-Plainsboro Teaching Hospital and relies on unconventional reasoning, extensive medical knowledge, and a willingness to challenge colleagues.

House's first name is Gregory, while his surname is House. The character is portrayed by Hugh Laurie, whose performance earned major awards and nominations. House is also deliberately modeled in part on Sherlock Holmes: both characters are exceptionally observant, live at a fictional address associated with the number 221B, and have a close friend who serves as a trusted sounding board.

Viewers sometimes confuse the character's name with the show's title. “House” is both the doctor's surname and the central word in House M.D., not the name of the hospital.
