The Wiesbaden class of light cruisers was a class of ships built by the German Kaiserliche Marine (Imperial Navy) shortly before the outbreak of World War I. Two ships were built in this class, Wiesbaden and Frankfurt. They were very similar to the preceding design, the Graudenz class, though they were armed with eight 15 cm SK L/45 guns instead of the twelve 10.5 cm SK L/45 guns on the earlier vessels. The ships had a top speed of 27.5 knots (50.9 km/h; 31.6 mph).
