SS Mauna Loa was a steam-powered cargo ship of Matson Navigation Company that was sunk in the bombing of Darwin in February 1942. She was christened SS West Conob in 1919 and renamed SS Golden Eagle in 1928. At the time of her completion in 1919, the ship was inspected by the United States Navy for possible use as USS West Conob (ID-4033) but was neither taken into the Navy nor ever commissioned.
