Katherine Mary Knight (born 24 October 1955) is an Australian murderer and the first woman in the country's history to be sentenced to life imprisonment without the possibility of parole. She was convicted for the murder of her partner, John Charles Thomas Price, in February 2000, and is currently imprisoned at the Silverwater Women's Correctional Centre in New South Wales. Knight stabbed Price to death, skinned him and then put his skin on a meat hook, which she had recently installed. She then cooked his head and parts of his body with the intention of feeding them to Price's children, but was stopped by police after an employee of his went to check on him after he had not been at work that day.
