James Wilson is the first name of House M.D.’s oncologist and Gregory House’s closest friend. Robert Sean Leonard portrayed Dr. James Evan Wilson throughout the series.
Wilson works at Princeton-Plainsboro Teaching Hospital and serves as the head of oncology. His empathy, patience, and concern for patients contrast with House’s confrontational style, although Wilson also has complicated personal relationships and makes ethically difficult choices.
The character is usually called Wilson by colleagues, which can make his first name less familiar to viewers. He is not to be confused with Dr. Lisa Cuddy, the hospital administrator, or Dr. Eric Foreman, another member of House’s diagnostic department.
