Valli di Comacchio

The Valli di Comacchio, meaning "fish basins of Comacchio", are a series of contiguous brackish lagoons situated to the south of Comacchio, close to the Adriatic coast of the Emilia-Romagna region in northern Italy. They lie within the comuni of Comacchio and Argenta in the province of Ferrara and the comune of Ravenna in the province of Ravenna.

The area, covering almost 17,000 hectares within the Parco regionale del Delta del Po, the regional park of the Po Delta, is classified as a Site of Community Importance and a Special Protection Area. It is also rated internationally important by the Ramsar Convention for the conservation and sustainable use of wetlands.
