Hannah Clarke (formerly Baxter; 8 September 1988 – 19 February 2020) was an Australian woman who was fatally burned in a petrol fire in her car, along with her three children, in a quadruple murder–suicide by her estranged husband, Rowan Baxter, on 19 February 2020 in Camp Hill, Queensland. The murders sparked a national debate about domestic violence in Australia, after reports emerged that Baxter had a history of violence and alleged misogyny and had been subjected to a domestic violence order (DVO) as well as child custody orders as recently as the month of the murders.
