The Königsberg class of light cruisers was a group of four ships commissioned into Germany's Kaiserliche Marine shortly before the end of World War I. The class comprised Königsberg, Karlsruhe, Emden, and Nürnberg, all of which were named after light cruisers lost earlier in the war. The ships were an incremental improvement over the preceding Wiesbaden-class cruisers, and were armed with a main battery of eight 15 cm (5.9 in) SK L/45 guns and had a designed speed of 27.5 knots.

A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Cruisers mounting larger guns and heavier armor relative to most light cruisers would come to be known as heavy cruisers, though the designation of 'light' versus 'heavy' cruisers would vary somewhat between navies. Through their history light cruisers served in a variety of roles, primarily as convoy escorts and destroyer command ships, but also as scouts and fleet support vessels for battle fleets.
