Pelješac is a peninsula in southern Dalmatia in Croatia. The peninsula is part of the Dubrovnik-Neretva County and is the second-largest peninsula in Croatia. From the isthmus that begins at Ston, to the top of Cape Lovišta, it is 65 km, or 40 miles long.
The name Pelješac is most likely derived from the name of a hill above the town of Orebić, which is Pelisac. This is a relatively new name for the peninsula. Throughout history, other names have been used such as Stonski Rat, Puncta Stagni, Ponta di Stagno and Sabbioncello.
The Bay of Mali Ston separates the peninsula from the Klek peninsula of Bosnia and Herzegovina and from the Croatian “mainland”. The Strait of Pelješac is located at its far western end, and it divides the peninsula from the island of Korčula. On the west part of the Peninsula is the highest summit of Pelješac, 961 m, or 3,153 ft.
