Thomas P. "Boston" Corbett (1832 – presumed dead 1894) was an American Union Army soldier who shot and killed Abraham Lincoln's assassin, John Wilkes Booth. He disappeared after 1888, but circumstantial evidence suggests that he died in the Great Hinckley Fire in 1894, although this remains impossible to substantiate.
He was a sergeant in the Union army who was part of the patrol that hunted John Wilkes Booth, the man who assassinated President Abraham Lincoln. Corbett and his men cornered Booth in a barn. Corbett, after demanding that Booth surrender, said that Booth tried to escape, so Corbett shot and killed him.
