Seebeckwerft A.G. was a German shipbuilding company, located in Bremerhaven at the mouth of the river Weser.
Seebeckwerft was founded in 1876 in Bremerhaven by Georg Seebeck (1845–1928), a young coppersmith, born in Brake at the Lower-Weser river.
In 1876 Georg Seebeck founded a small metal-processing workshop in Geestemünde, a part of the city of Bremerhaven.
In 1928 the Seebeckwerft became a member of the Deschimag, a cooperation of several German shipyards under the leadership of the Bremen-shipyard A.G. Weser.
The design of Koningin Beatrix (1986) was also by A.G. Weser Seebeckwerft, but she was constructed at Van der Giessen de Noord.
