Donald Joseph Watt (born 10 August 1918) is an Australian former Army soldier and the author of a literary hoax, a fictitious Holocaust memoir entitled Stoker: The Story of an Australian Soldier who Survived Auschwitz-Birkenau, published in 1995 by Simon & Schuster. Only the disclosure of Watt's fabrications altered the status of the book which was initially praised by various Jewish organizations as the most important work written in Australia.
