SMS Siegfried was the lead ship of the six-member Siegfried class of coastal defense ships (Küstenpanzerschiffe) built for the German Imperial Navy. Her sister ships were Beowulf, Frithjof, Heimdall, Hildebrand, and Hagen. Siegfried was built by the Germaniawerft shipyard between 1888 and 1890, and was armed with a main battery of three guns. She served in the German fleet throughout the 1890s and was rebuilt in 1903–1904. She served in the VI Battle Squadron after the outbreak of World War I in August 1914, but saw no action. Siegfried was demobilized in 1915 and used as a barracks ship thereafter. She was ultimately broken up for scrap in 1920.
