Francis II (German: Franz II.; 12 February 1768 – 2 March 1835) was the last Holy Roman Emperor (from 1792 to 1806) and, as Francis I, the first Emperor of Austria, from 1804 to 1835. He assumed the title of Emperor of Austria in response to the coronation of Napoleon as Emperor of the French. Soon after Napoleon created the Confederation of the Rhine, Francis abdicated as Holy Roman Emperor. He was King of Hungary, Croatia and Bohemia. He also served as the first president of the German Confederation following its establishment in 1815.

Francis II continued his leading role as an opponent of Napoleonic France in the Napoleonic Wars, and suffered several more defeats after Austerlitz. The marriage of his daughter Marie Louise of Austria to Napoleon on 10 March 1810 was arguably his severest personal defeat. After the abdication of Napoleon following the War of the Sixth Coalition, Austria participated as a leading member of the Holy Alliance at the Congress of Vienna, which was largely dominated by Francis' chancellor Klemens Wenzel, Prince von Metternich culminating in a new European map and the restoration of most of Francis' ancient dominions. Due to the establishment of the Concert of Europe, which largely resisted popular nationalist and liberal tendencies, Francis was viewed as a reactionary later in his reign.

Francis II's grandchildren include Napoleon II (Napoleon's only legitimate son), Franz Joseph I of Austria, Maximilian I of Mexico, Maria II of Portugal and Pedro II of Brazil.
