Poppy Shakespeare is a 2006 novel about mental illness by Clare Allan. It tells the story of day patients at a mental health hospital. The central characters are Poppy Shakespeare, a new patient, and "N", a long-term patient. Poppy arrives at the hospital strongly asserting that she is sane and demanding to be released from the program. To gain legal aid she must first prove she is sick so that she can get "MAD money", a.k.a. state benefits. She is befriended by N, who helps her work the system.
