The Radetzky class was a group of three semi-dreadnought battleships built for the Austro-Hungarian Navy between 1907 and 1910. All ships were built by the STT shipyard in Trieste. They were the last pre-dreadnoughts built by the Austro-Hungarians, and the penultimate class of any type of Austro-Hungarian battleship completed. The class comprised three ships: Radetzky, Erzherzog Franz Ferdinand, and Zrínyi. They were armed with four 30.5-centimeter (12.0 in) guns in two twin turrets and eight 24 cm (9.4 in) guns in four twin turrets.

Commissioned only a few years before the outbreak of World War I, the ships had limited service careers. All three of the battleships conducted training cruises in the Mediterranean Sea in 1912. In 1913, they took part in an international naval demonstration in the Ionian Sea that protested the Balkan Wars. After Italy declared war on Austria-Hungary and the other Central Powers in 1915, the three Radetzky-class ships bombarded coastal targets in the Adriatic Sea. After 1915, their participation in the war became minimal. All three ships were handed over to Italy after the end of the war, and broken up for scrap between 1920 and 1926.
