Dame Ruth Elizabeth Warrick (June 29, 1916 – January 15, 2005), DM, was a long-time American singer, Hollywood Golden-Age actress and political activist, best known for her role as Phoebe Tyler on All My Children, which she played regularly from 1970 until her death in 2005.

She celebrated her 80th birthday by attending a special screening of Citizen Kane to a packed, standing-room-only audience, to which she spoke afterward. (She made her film debut as Kane's first wife.) Over the years, she collected several books about Orson Welles and Citizen Kane, in which she would write "Property of Ruth Warrick, Mrs. Citizen Kane".
