Canale di Stagno Piccolo

Bay of Mali Ston is a bay in the Adriatic Sea, enclosed by the Pelješac peninsula and the mainland. The name primarily refers to the innermost, eastern part of the bay, while the name Channel of Mali Ston is used for the channel between the peninsulas of Klek and Pelješac, in the west. The two bodies of water are located in Croatia's and partly in Bosnia and Herzegovina's territorial waters.

The bay is named after the village of Mali Ston. Its southernmost point is at the isthmus of the Pelješac peninsula, while its mouth is located roughly north of Hodilje. The Channel, in turn, extends from there to the line between Cape Blaca on Pelješac and Cape Međed on the shore, located south of Komarna.
