Sušac (Croatian pronunciation: [sǔːʃat͡s]) is a small rocky island in the Adriatic Sea with an area of 4.03 km2, and 16.4 km[1] of coastline southwest of Korčula and Lastovo, on the halfway to the island of Vis, in Croatia.
The coast consists of slopes and cliffs over 100 m tall, but the opposite side features a natural harbour.
A 19th-century lighthouse is built on top of the island.
The island is also known for its little lake, which is connected to the sea through a siphon 15 m deep.
