William Green (7 June 1784 – 27 January 1881) was an English rifleman of the 95th Regiment who served in the Napoleonic Wars. He was the author of a memoir entitled "A brief outline of the Travels and Adventures of William Green (late Rifle Brigade) during a period of ten years in the British Service", one of the few accounts by an enlisted man of life in Wellington's Army. As such it has served as a primary source for many historians.
