Carter Henry Harrison III (February 15, 1825 – October 28, 1893) was an American politician who served as mayor of Chicago, Illinois, from 1879 until 1887 and from 1893 until his assassination. He previously served two terms in the United States House of Representatives. Harrison was the first cousin twice removed of President William Henry Harrison, whose grandson, Benjamin Harrison, had also been president from 1889–1893. He was also the father of Carter Harrison IV, who would follow in his father's footsteps, and would serve five terms as the mayor of Chicago himself.
