Empress Augusta Bay is a bay on the western side of the island of Bougainville Island, within the Autonomous Region of Bougainville in northeastern Papua New Guinea.
It is a subsistence fishing area for the people of Bougainville.
During the 1970s and 1980s the bay was seriously polluted by copper tailings from the world's largest copper mine, Panguna, operated by Rio Tinto Group.
This issue contributed to the formation of the secessionist Bougainville Revolutionary Army and a civil war on the island between 1989 and 1997.
