George Dean (14 November 1867 – 7 May 1933) was a ferry boat master in Sydney, Australia, who was charged with attempting to poison his wife. A large part of the Sydney public came to believe that Dean was innocent and that his wife and her mother had conspired against him. Although Dean was very likely guilty, his death sentence was commuted and he was later released on a free pardon. He was subsequently convicted of perjury and spent nine years in jail.
