The Secret River is a 2005 historical novel by Kate Grenville about an early 19th-century Englishman transported to Australia for theft. The story explores what might have happened when Europeans colonised land already inhabited by Aboriginal people. The book has been compared to Thomas Keneally's The Chant of Jimmie Blacksmith and to Peter Carey's True History of the Kelly Gang for its style and historical theme.
