Katherine Mary Clutterbuck CSC MBE (October 1860 in Wiltshire, England – 31 July 1946 in Nedlands, Western Australia), usually known as Sister Kate, was an Anglican nun who pioneered a cottage home system for looking after orphan babies and children in Western Australia. She later became well known for her work with Indigenous Australian children who were selected according to a criterion of skin colour and sent to her homes to groom the young "nearly white" children for absorption into the white community. These children would later be described as part of the Stolen Generation.
