The Gulf of Drin or Bay of Drin (Albanian: Gjiri i Drinit or Pellgu i Drinit) is an ocean basin of the Adriatic Sea within the Mediterranean Sea along the northern coast of Albania. Roughly scythe-shaped, it extends immediately from the Delta of the Buna in the north, across the port city of Shëngjin, to the Cape of Rodon in the south. The shoreline of the gulf is a shallow combination of sandy beaches, sand dunes, capes, salty and fresh water wetlands, estuaries, pine and coastal forests, reed beds and coastal meadows.
The shoreline of the gulf has a length of approximately 60 kilometres and is dotted with cliffs and beaches fed by fluvial imputes. The region is drained by numerous rivers and has formed a characteristic ecosystem and biodiversity. It is named after the Drin River that runs through a mountainous area towards the coast, however, the Ishëm and Mat also drain into the gulf. In consideration to the flat landscape, the gulf's shoreline are dotted with extensive wetlands and lagoons that continuously change in size and shape.
