The IRIS Kharg (Persian: خارگ‎) was a modified Ol-class fleet replenishment oiler of the Islamic Republic of Iran Navy, named after Kharg Island. Built by Swan Hunter in the United Kingdom and launched in 1977, she was delivered to Iran in 1984. On 2 June 2021, Kharg caught fire and sank near the Iranian town of Jask and the Strait of Hormuz in the Gulf of Oman.
