What is the full name of Dr. Wilson in House M.D.?

The full name of Dr. Wilson in House M.D. is James Evan Wilson.

James Wilson is the head of oncology at Princeton-Plainsboro Teaching Hospital and Gregory House's closest friend. Robert Sean Leonard played him throughout the series, giving the character a compassionate counterbalance to House's abrasive personality and unusual diagnostic methods.

Wilson's first and middle names appear in character information and story material, although the show usually calls him simply Wilson. His specialty is important to the series because oncology brings him into contact with patients facing serious illness, ethical choices, and difficult prognoses.

House and Wilson have a long, complicated friendship. Wilson frequently challenges House's behavior, yet he also understands House better than most colleagues. Their relationship is a recurring emotional thread, and Wilson's personal life—including his marriages and family relationships—often intersects with the hospital's medical cases.
