The Dresden class was a pair of light cruisers built for the Imperial German Navy in the early part of the 20th century. The class comprised SMS Dresden, the lead ship, and SMS Emden. Both ships were laid down in 1906; Dresden was launched in 1907, and Emden followed in 1908. They entered service in 1908 and 1909, respectively. The design for the ships was an incremental improvement over the preceding Königsberg class, being slightly larger and slightly faster, but with the same primary armament of ten 10.5 cm (4.1 in) guns. Dresden and Emden were powered by steam turbines and triple expansion engines, respectively, as part of continued experiments with the new turbine technology.

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.
