Thomas H. "Boston" Corbett (January 29, 1832 – presumed dead c. September 1, 1894) was an American Union Army soldier who shot and killed U.S. president Abraham Lincoln's assassin, John Wilkes Booth. Corbett was initially arrested for disobeying orders, but was later released on the orders of Secretary of War Edwin Stanton, who referred to Corbett as "the patriot" upon dismissing him. He was largely considered a hero by the media and the public.
Known for his devout religious beliefs and eccentric behavior, Corbett drifted around the United States before disappearing circa 1888. Circumstantial evidence suggests that he died in the Great Hinckley Fire in September 1894, but that remains impossible to substantiate.
