Piskera is a small uninhabited island in the Croatian part of the Adriatic Sea. It is one of the Kornati Islands in central Dalmatia and its area is 2.66 km². Its coastline is 10.64 km long. Although uninhabited, a marina with 150 berths operated by ACI Club is located on the island, open between March and October every year. Marina Piskera is sheltered from the worst of the winds by the offshore island Panitula Vela. In the past, Piskera and Panitula Vela were important centers for fishing and when the Venetians controlled the Kornati Islands, they had a customs post here for taxing the fish catch.
