Prežba is a small inhabited island in the Croatian part of the Adriatic Sea, located northwest of the island of Lastovo in southern Dalmatia. It is connected to Lastovo by a bridge at the village of Pasadur on Lastovo. Prežba's area is 2.81 km2,[1] but its coastline is 14.23 km long, due to the large number of coves on the island.
