Archduke Stephen Francis Victor (German: Stephan Franz Viktor; Hungarian: István Ferenc Viktor; 14 September 1817 – 19 February 1867) was a member of the House of Habsburg-Lorraine and the last Palatine of Hungary, serving from 1847 to 1848.

His mother died shortly after giving birth to him and his twin sister, Archduchess Hermine of Austria.

He spent much of his childhood in Buda and at the family estate in Alcsút and received an excellent education.

In 1843, he gained the rank of lieutenant field marshal in the service of the Austrian Army and Emperor Ferdinand I of Austria appointed him governor of Bohemia.

Stephen succeeded him as Palatine of Hungary on 12 November 1847 but resigned in September 1848 as a result of the Hungarian Revolution.
