Truddi Chase (born June 13, 1939, near Rochester, New York) is the author of the book When Rabbit Howls (1987), an autobiography about her experiences after being diagnosed with multiple personality disorder.
Chase claimed in her autobiography that she was repeatedly and violently sexually and physically abused by her stepfather and beaten and neglected by her mother during her childhood and teenage years. Chase claims to have remembered the molestation and abuse from the age of two onwards but that she could not focus on details before going into therapy. It was during sessions with a hypnotherapist that she concluded that she had multiple personalities.
Chase's book is unique in that it is only the second book written by a psychiatric client about her experience of multiple personalities (the first was written in 1908 ). Unlike most people documented with MPD, Chase refused to integrate her personalities, instead thinking of them as a cooperating team.
Chase was the first guest on Oprah Winfrey's radio program, and one of the first on The Oprah Winfrey Show. She returned in 1990 for a second interview.  She was portrayed by Shelley Long in the 1990 telemovie Voices Within: The Lives of Truddi Chase.
