Kelanoa Harbour is a harbour on the north coast of Huon Peninsula, Papua New Guinea serving the town of Kelanoa. It is a large bay with an impenetrable reef and a small island.
History
The Imperial Japanese Navy submarine Japanese Kaidai class submarine I-181 was beached upon Gneisenau Point in Kelanoa Harbour, after it was attacked in Vitiaz Strait by a United States Navy destroyer and a PT boat on 16 January 1944 and lost with all (89) hands.
Some sources claim the I-181 was sunk in St. George's Channel on the same day by US Navy aircraft.
