The MS Ionian Star is a ferry built 1971 by Aalborg Vaerft as Prinsessan Désirée for Swedish Sessanlinjen's ferry service between Gothenburg and Frederikshavn.

After Stena Line took over this route, she was used by the in-house company Lion Ferry as Lion Princess between Karlskrona and Gdynia.

Since 1994 her name was Bohus, operating for Scandi Line between Sandefjord and Strömstad.

2019 the ship was sold to European Ferries.

In August she was renamed Ionian Star and sailed under Panama flag between Brindisi in Italy and Vlora in Albania.
