Charles James Stewart Bethune (12 August 1838 – 18 April 1932) was a Canadian Anglican priest and entomologist.
He was along with William Saunders, a founder of the Entomological Society of Canada editing its journal The Canadian Entomologist for its first 30 years.
He then worked as a priest for nine years and served as headmaster of Trinity College School, Port Hope from 1870 to 1899.
At a meeting of the American Association for the Advancement of Science in 1872, he disputed with Samuel Scudder on evolution and in 1910 he stated that the main reason for maintaining butterfly collections was because "they were created because the Lord has an eye on the beautiful.
"[2][3][4] Bethune was married to Harriet Alice Mary from 1863 until her death in a carriage accident in July 1898.
