Olive Muriel Pink (17 March 1884 – 6 July 1975) was an Australian botanical illustrator, anthropologist, gardener, and activist for Aboriginal rights. Pink spent much of her life agitating and being a passionate advocate for improved rights and conditions for Australia's Indigenous people. She never married, having lost a "very dear friend" Harold Southern, a fellow artist who was killed at Gallipoli in 1915. In her later years, Pink concentrated on botanical pursuits and established the currently named Olive Pink Botanic Garden in Alice Springs.
