Huon Gulf is a large gulf in eastern Papua New Guinea. It is bordered by Huon Peninsula in the north. Both are named after French explorer Jean-Michel Huon de Kermadec. Huon Gulf is a part of the Solomon Sea. Its northern boundary is marked by Cape Cretin, southern by Cape Longerue. The coast, which quickly increases in elevation from the beach, is bordered by the Rawlinson Range to the north and the Kuper Range to the west, which rises to about 600 m (2,000 ft). Lae, capital of the Morobe Province, is located on the northern coast of the gulf.
Markham Bay forms the north-western corner of Huon Gulf, where the Markham River ends.
