Aktien-Gesellschaft Vulcan Stettin was a German shipbuilding and locomotive building company. Founded in 1851, it was located near the former eastern German city of Stettin, today Polish Szczecin. Because of the limited facilities in Stettin, in 1907 an additional yard was built in Hamburg. The now named Vulcan-Werke Hamburg und Stettin Actiengesellschaft constructed some of the most famous civilian German ships and it played a significant role in both World Wars, building warships for the Kaiserliche Marine and the Kriegsmarine later.
