King Island is one of the islands that make up the state of Tasmania, Australia. It is located in the Roaring Forties of Bass Strait, off the north-western tip of the main island of Tasmania, about half way between Tasmania and the mainland state of Victoria. The southernmost point is called Stokes Point and the northernmost point is called Cape Wickham. There are three small islands surrounding King Island, namely New Year Island and Christmas Island situated to the northwest, and a smaller island called Councillor Island to the east.
King Island was named after Governor King of New South Wales, whose territory at the time included what is now Tasmania. The local government area of the island is King Island Council. The population in 2007 was 1,723.
