The Brummer class consisted of two light mine-laying cruisers built for the Imperial German Navy in World War I: SMS Brummer and SMS Bremse. When the war broke out, the Germans had only two older mine-laying cruisers. Although most German cruisers were fitted for mine-laying, a need for fast specialized ships existed. The Imperial Russian Navy had ordered sets of steam turbines for the first two ships of the Svetlana-class cruisers from the AG Vulcan shipyard in Stettin. This machinery was confiscated on the outbreak of war and used for these ships. Both vessels were built by AG Vulcan.

SMS Brummer was a minelaying light cruiser of the German Kaiserliche Marine; she was the lead ship of her class. Her sister ship was Bremse. Brummer was laid down at AG Vulcan's shipyard in Stettin, Germany on 24 April 1915 and launched on 11 December 1915 and completed on 2 April 1916. Armed with a main battery of four 15-centimeter (5.9 in) guns in single mounts, she carried 400 mines.
