SMS Prinz Eugen (His Majesty's Ship Prinz Eugen) was the third of four dreadnought battleships built for the Austro-Hungarian Navy. Prinz Eugen was named for Prince Eugene of Savoy, a Habsburg general and statesman during the 17th and 18th centuries most notable for defeating the Ottoman Empire at the Battle of Zenta in 1697. The ship was armed with a main battery of twelve guns in four triple turrets. Constructed shortly before World War I, she was built at the Stabilimento Tecnico Triestino shipyard in Trieste, where she was laid down in January 1912 and launched in November that same year. Commissioned into the Austro-Hungarian Navy just 10 days after the assassination of Archduke Franz Ferdinand, Prinz Eugen was a member of the 1st Battleship Division of the Austro-Hungarian Navy at the beginning of the war alongside the other ships of her class, and was stationed out of the Austro-Hungarian naval base at Pola.

After the sinking of Szent István, Prinz Eugen and the remaining two ships of her class, and , returned to port in Pola where they remained for the rest of the war. Facing defeat in the war in October 1918, the Austro-Hungarian government decided to transfer the bulk of its navy to the newly formed State of Slovenes, Croats and Serbs in order to avoid having to hand the ship over to the Allies. This transfer however was not recognized by the Armistice of Villa Giusti, signed between Austria-Hungary and the Allies in November 1918. Under the terms of the Treaty of Saint-Germain-en-Laye, Prinz Eugen was handed over to France.
