Kamieński Lagoon is a lagoon on the Oder River in north-western Poland. It is part of the Dziwna. Both the lagoon and the Dziwna are part of Poland's internal waters.Until 1945, the lagoon was referred to by its German name of Camminer Bodden.[citation needed] In 1949, it officially became called Kamieński Zalew, and in 1991 the words in its name were reversed, its new name being Zalew Kamieński.
