Roviana is the name given to a large lagoon on the south coast of New Georgia in the Western Solomon Islands, to the people living on the shores of this lagoon, and to the language spoken to these people. The people of Roviana were one of the few peoples in the Solomon Islands to practice headhunting. In the second half of the nineteenth century, the Roviana and their allies conducted extensive headhunting raids upon islands to the east, resulting in widespread depopulation.
