Lies off the south end of Moresby Island, from which it is separated by the Houston Stewart Channel. It is an adaption of the old Haida name for the island, meaning to-the-south. About 15 miles long and perhaps 8 miles across at its widest, it was selected in 1853 to bear the name of Commander James Prevost, master of the Virago during the survey of the Houston Stewart Channal by G.H. Inskip. When the Geographic Board realized that Prevost's name had also been applied to an island off the east coast of Vancouver Island, they reinstated the old Haida name to the island off the south end of the Charlottes, and in 1904 it became KUNGHIT ISLAND for all successive maps.
One of Ingraham's 1791-92 charts showed the island as KINGSETT, but this is generally believed to be a variation of Kunghit.
The place names of Kunghit Island include many of the crew of the "Columbia Rediva" as well as those of whalers.

Kunghit is derivation of the traditional Haida First Nation name for the island, Gaang.xid Gwaayaay. The name Gaang.xid means “to the south,” and Gwaayaay means “island.” Kunghit Island is the southernmost island of the Haida Gwaii (Queen Charlotte Islands). The isle was renamed Prevost Island in 1853 by British Admiralty Surveyors, presumably after Commander James C. Prevost, the commanding officer of the HMS Virago, which was sailing around the Haida Gwaii that year. However, the Geographic Board of Canada reversed that decision 51 years later, to prevent confusion with the other Prevost Island located near Saltspring Island.
