The Erste Donau-Dampfschiffahrts-Gesellschaft, or Donaudampfschiffahrtsgesellschaft (DDSG) (the word means Danube Steamboat Shipping Company) was a shipping company founded in 1829 by the Austrian government for transporting passengers and cargo on the Danube. In 1880, the DDSG was the world's largest river shipping company with more than 200 steamboat ships and about 1000 cargo tubs.
In 1991 the company was split into a passenger transportation enterprise and a cargo transport company. The company was sold to a private owner in 1993. Today the DDSG exists in the form of the two private companies DDSG-Blue Danube Schiffahrt GmbH (passenger transport) and the DDSG-Cargo GmbH.
