The Danube–Black Sea Canal (Romanian: Canalul Dunăre – Marea Neagră) is a canal in Romania, which runs from Cernavodă, on the Danube, to Constanţa (southern arm, as main branch), and to Năvodari (northern arm), on the Black Sea. Administrated from Agigea, it is an important part of the European canal system that links the North Sea (through the Rhine–Main–Danube Canal) to the Black Sea.
