Archduke Ferdinand Karl Joseph of Austria-Este (25 April 1781 – 5 November 1850) was the third son of Archduke Ferdinand of Austria-Este and of his wife Princess Maria Beatrice Ricciarda d'Este, last member and heiress of the House of Este.
He succeeded in holding the Bavarian division of Prince Karl Philipp von Wrede in Iglau thereby and preventing it from joining the Battle of Austerlitz.
In April he invaded the Duchy of Warsaw hoping to encourage a local uprising against Napoleon (see Polish–Austrian War).
In 1815 in the War of the Seventh Coalition against France, Ferdinand commanded two divisions of the Austrian Reserve.
In 1830 Ferdinand was appointed military and civil governor of Galicia, taking up residence in Lemberg.
