The Brandenburg class consisted of four pre-dreadnought battleships built for the German Kaiserliche Marine, the first modern battleships of the fleet. The four ships of the class—Brandenburg, Wörth, Weissenburg, and Kurfürst Friedrich Wilhelm—were the first ocean-going capital ships built for the German fleet in nearly two decades, owing to reluctance in the Reichstag to fund large projects. They followed a series of small coastal defense ships, and though in retrospect they anticipated the buildup that created the High Seas Fleet, they were ordered as part of a construction program that reflected the strategic and tactical confusion that affected many navies in the 1880s. The design process that resulted in the Brandenburg class was very lengthy, with proposals that ranged from outdated casemate ships to versions with two twin-gun turrets placed side by side. The designers ultimately settled on ships that were armed with an unusual main battery of six 28 cm (11 in) guns at a time when all foreign battleships were built with four or fewer heavy guns.

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.
