Florence Emily Green (12 April 1862 – 5 April 1926) was an Australian headmistress. She was the founding headmistress at the New England Girls' School in New South Wales.

Green was born in 1862 in Oamaru, New Zealand. Her parents were Eliza Green (née Dutton) and her husband, the Reverend Samuel Dutton Green. Her elder brother Arthur Vincent Green had been born in 1857. They were brought up in Adelaide, Wales and Scotland.^[1] Her younger brother was educated at Trinity College, Melbourne^[2] and ordained in 1880,^[3] but she was educated at home and at a private school in Melbourne. She then attended the Australian College of Theology where she achieved first-class honours.

Green paid for the education of Ethel Florence Lindesay Richardson. In Richardson's coming of age novel, The Getting of Wisdom, written under the pen name of Henry Handel Richardson, Green was depicted as Miss Isabella, and Arthur as her brother, the Rev Mr Shepherd. Richardson is said to have described Green "maliciously but accurately".^[1]
