David Curtiss "Steve" Stephenson (21 August 1891 – 28 June 1966) was an American politician who was appointed in 1923 as a Grand Dragon (state leader) of the Ku Klux Klan in the U.S. state of Indiana, and head of recruiting for seven other states. Later that year, he led those groups to independence from the national KKK organization. Amassing wealth and political power in the Republican Party, he was considered to have been one of the most prominent national Klan leaders. He had close relationships with numerous Indiana politicians, including Governor Edward L. Jackson, a Klan member elected to office in 1924.
