Jadrolinija is a Croatian sea shipping company. It is a state-owned company and its main mission is connecting Croatian islands to the mainland by operating regular passenger and cargo transport services. The company mainly operates car ferries on domestic routes along the Croatian coast, as well as international routes across the Adriatic Sea to Italy (to ports at Ancona and Bari).
Jadrolinija currently operates a fleet of 56 vessels: it has four large ferries named Dubrovnik, Marko Polo, Liburnija and Zadar which are used on long range and international routes, 37 smaller ferries used for local passenger service, eight catamarans, one hydrobus and five conventional ships. The fleet's total carrying capacity is 3,600 vehicles and 27,540 passengers. In 2007 Jadrolinija transported a total of 9.4 million passengers and 2.4 million automobiles.
Jadrolinija was founded in Rijeka on 20 January 1947 as a continuation of various smaller shipping companies which had operated along the Croatian coast since 1872.2
