Dr. Cuddy’s first name in House M.D. is Lisa.
Lisa Cuddy is the dean of medicine and hospital administrator at Princeton-Plainsboro Teaching Hospital. She supervises Gregory House, manages the institution’s practical demands, and frequently clashes with him over rules, patient care, staffing, and his willingness to take risks.
The character was played by Lisa Edelstein. Cuddy’s professional authority makes her one of the few people who can regularly impose consequences on House, although their relationship develops beyond a simple supervisor-and-employee conflict over the course of the series.
This answer can be confused with Allison Cameron, another doctor in House’s department, or Stacy Warner, House’s former partner. The character’s first name is Lisa, matching the first name of the actor who portrayed her, but the two facts are separate.
