Deutsche Schiff- und Maschinenbau Aktiengesellschaft (abbreviated Deschimag) was a cooperation of eight German shipyards in the period 1926 to 1945. The leading company was the shipyard AG Weser in Bremen.

The Deschimag was founded in 1926 when influential Bremen merchants and bankers decided to found a cooperation of great German shipbuilding companies under the leadership of the shipyard AG Weser. The intention was to coordinate and concentrate activities of German shipyards for higher efficiency but last not least mainly to support Bremen's shipyard AG „Weser“ in the upcoming economic and financial crisis of 1930s. While the largest shipbuilding companies in Germany as Blohm & Voss and Bremer Vulkan AG because of their own strong market position at that time were not interested in this cooperation, eight other large German shipyards merged. These were:

• Actien-Gesellschaft "Weser", Bremen (closed 1983)
• Vulkan-Werke Hamburg A.G., Hamburg (1930 sold to Howaldtswerke Kiel)
• Joh. C. Tecklenborg A.G., Wesermünde (closed 1928)
• AG Vulcan Stettin, Stettin (closed 1928)
• G. Seebeck A.G., Geestemünde (1988 merged to Schichau Seebeckwerft, closed 2009)
• Actien-Gesellschaft "Neptun", Rostock (bankruptcy 1935, since 1997 part of the shipbuilding company Meyer Werft GmbH, Papenburg)
• Nüscke & Co. A.G., Stettin (bankrupt 1928)
• Frerichswerft A.G., Einswarden (gave up shipbuilding 1935, afterwards Weser Flugzeugbau aircraft production)

Deschimag became the greatest shipbuilding company in Germany with about 15,000 workers which was about 28% of the total German shipbuilding industry workforce at that time. But in the following years most of these companies were closed, went bankrupt or were sold to other companies (see above). At least only AG Weser and Seebeckwerft survived this process of concentration and reduction of shipbuilding capacities. In 1941 Krupp, then the most important German engineering and armaments conglomerate, acquired a majority shareholding in both shipyards.

While AG Weser concentrated its activities upon building of merchant ships with an increasing amount of warships later, Seebeck built only smaller vessels and concentrated on ship maintenance and repair.

Because of diversification and to create new jobs Deschimag also diversified into aircraft construction. In 1933 the Weser Flugzeugbau GmbH – abbreviated Weserflug – was founded. It started making aircraft components and later complete aircraft at different places in Germany, one of them was the former shipyard Frerichswerft AG. In 1936 the Weserflug separated from the Deschimag and became an independent company. It became the fourth largest aircraft manufacturer in Germany in World War II, but only as a licensee of other German aircraft companies, mainly Dornier and Junkers.

Deschimag was dissolved after war but AG Weser and Seebeck AG shipyards again survived and continued in shipbuilding. Due to mismanagement and unsatisfactory and too late responses to market demands AG Weser was declared bankrupt in 1983 and operations were shut down while Seebeck shipyard became part of the Bremer Vulkan Verbund AG. Later in 1988 it merged with Schichau Shipyard to SSW Schichau Seebeck Shipyard GmbH, which closed in 2009.
