SMS Zrínyi was a Radetzky-class semi-dreadnought battleship (Schlachtschiff) of the Austro-Hungarian Navy, named for the Zrinski, a Croatian-Hungarian noble family. Zrínyi and her sisters, Erzherzog Franz Ferdinand and Radetzky, were the last pre-dreadnoughts built for the Austro-Hungarian Navy.

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.
