Robert Geoffrey Hewett "Bob" Green AM (4 November 1925 – 29 August 2013) was an Australian naturalist, photographer, conservationist, and long-term Curator of the Queen Victoria Museum and Art Gallery in Launceston, Tasmania.
He grew up on the family farm at Antill Ponds in the Tasmanian Midlands where he developed a strong interest in natural history.
In 1959 Green was appointed the honorary ornithologist at the Queen Victoria Museum, the start of a thirty-year association with the institution.
As well as building up the museum's collections of natural history and historical material, he also amassed a large personal collection of the eggs of Tasmanian birds, which was eventually donated to the National Museum of Australia in Canberra in 2002.
He has been recognised in the scientific names of several animals, including a parasitic fly, a bird louse, three fleas, a mite, two fish, a skink (Carinascincus greeni),[2] and a subspecies of the Tasmanian endemic Scrubtit (Acanthornis magnus greenianus).
