In House M.D., what is the real name of the doctor nicknamed Thirteen?

Remy Hadley is the real name of the doctor nicknamed Thirteen in House M.D.

Thirteen, played by Olivia Wilde, joins House’s diagnostic team during the fourth season. Her nickname comes from the number assigned to her during the team-selection process after the previous diagnostic fellows leave. The number remains her best-known identifier even after House and the other doctors learn her surname.

Hadley is a physician with a guarded personality and a strong concern for patient autonomy. Her storyline includes the discovery that she carries the gene for Huntington’s disease, a progressive inherited neurological disorder. The possibility of developing the disease shapes her relationships, career choices, and attitude toward uncertainty.

The character’s full name is sometimes confused with the nickname itself or with other members of House’s rotating teams. “Thirteen” is not her legal first name; it is the number by which she was identified during the hiring contest. Remy Hadley is the canonical character name used in series references.
