What is the name of Cuddy's daughter in House M.D.?

Lisa Cuddy's adopted daughter in House M.D. is named Rachel. Cuddy adopts Rachel during the show's fifth season after deciding to become a parent.

Rachel's adoption becomes an important part of Cuddy's personal storyline and affects her relationship with Gregory House. The child appears in hospital and home scenes, while Cuddy balances parenting with her role as Princeton‑Plainsboro's dean of medicine. House sometimes helps with childcare, creating comic and emotional situations.

Rachel is not Cuddy's biological daughter, and the adoption plot is separate from Cuddy's earlier fertility concerns. The character's name is occasionally confused with names of other patients or staff children, but Rachel is the canonical name used throughout her appearances.
