MV Rhosus was a general cargo ship that was abandoned in Beirut, Lebanon, after the ship was declared unseaworthy and the charterers lost interest in the cargo. The 2,750 tonnes of ammonium nitrate which the ship was carrying was confiscated and brought to shore in 2014, and later contributed to the catastrophic 2020 Beirut explosion. The vessel's owner at the time of abandonment was Cyprus-based Russian businessman Igor Grechushkin. The ship sank in the Port of Beirut in 2018.
