The Braunschweig-class battleships were a group of five pre-dreadnought battleships of the German Kaiserliche Marine built in the early 1900s. They were the first class of battleships authorized under the Second Naval Law, a major naval expansion program. The class comprised five ships—Braunschweig, Elsass, Hessen, Preussen, and Lothringen—and they were an improvement over the preceding Wittelsbach class. The Braunschweigs mounted a more powerful armament of 28 cm (11 in) and 17 cm (6.7 in) guns. Less than two years after the first members of the class entered service, the ships were rendered obsolescent by the British all-big-gun battleship Dreadnought, which curtailed their careers.

Pre-dreadnought battleships were sea-going battleships built from the mid- to late- 1880s to the early 1900s. Their designs were conceived before the appearance of HMS Dreadnought in 1906 and their classification as "pre-dreadnought" is retrospectively applied. In their day, they were simply known as "battleships" or else more rank-specific terms such as "first-class battleship" and so forth. The pre-dreadnought battleships were the pre-eminent warships of their time and replaced the ironclad battleships of the 1870s and 1880s.
