Charlotte Hilton Green (17 October 1889 – 26 March 1992) was a writer and naturalist, environmentalist, educator and clubwoman.
She was born in Dunkirk, New York, but moved to Raleigh, North Carolina in 1920, where she lived most of her life.
Green met many ornithologists, and in 1923 began one of the earliest bird banding stations in North Carolina.
In 1938 she and her husband bought a large plot of land in Raleigh which she gradually developed into a wildlife sanctuary and arboretum, called Greenacres.
Her newspaper columns, books, and promotion of nature study did much to further the understanding of the importance of wildlife and the environment.
