SMS Fürst Bismarck was Germany's first armored cruiser, built for the Kaiserliche Marine before the turn of the 20th century. The ship was named for the German statesman Otto von Bismarck. The design for Fürst Bismarck was an improvement over the previous Victoria Louise-class protected cruisers—Fürst Bismarck was significantly larger and better armed than her predecessors.

The armored cruiser was a type of warship of the late 19th and early 20th centuries. It was designed like other types of cruisers to operate as a long-range, independent warship, capable of defeating any ship apart from a battleship and fast enough to outrun any battleship it encountered.
