Zhenyuan was an ironclad battleship built for the Chinese Beiyang Fleet. She was the second and final member of the Dingyuan class, which included one other vessel, Dingyuan, both of which were built in Germany in the early 1880s. Delivery of the two ironclads was delayed by the Sino-French War of 1884–1885. The ships were armed with a main battery of four 12 in (305 mm) guns in a pair of gun turrets, making them the most powerful warships in East Asian waters at the time.

The Beiyang Fleet was one of the four modernized Chinese navies in the late Qing dynasty. Among the four, the Beiyang Fleet was particularly sponsored by Li Hongzhang, one of the most trusted vassals of Empress Dowager Cixi and the principal patron of the "self-strengthening movement" in northern China in his capacity as the Viceroy of Zhili and the Minister of Beiyang Commerce (北洋通商大臣). Due to Li's influence in the imperial court, the Beiyang Fleet garnered much greater resources than the other Chinese fleets and soon became the dominant navy in Asia before the onset of the 1894–1895 First Sino-Japanese War. It was the largest fleet in Asia and the 8th in the world during the late 1880s in terms of tonnage.
