Ernest Ewart Unwin (13 July 1881 – 20 September 1944) was an Australian Quaker educationist. Born in England, he held a variety of positions in several Quaker schools before lecturing at the University of Leeds, his alma mater. A conscientious objector during World War I, he emigrated to Australia in 1923 to headmaster a school in Hobart. After enlisting the financial assistance of Quaker organisations in the area, Unwin oversaw great expansion of the Tasmanian education system, creating and serving on several Boards of Education at local and state level for both community schools and the University of Tasmania.
