The North Bougainville or West Bougainville languages are a small language family spoken on the island of Bougainville in Papua New Guinea. They were classified as East Papuan languages by Stephen Wurm, but this does not now seem tenable, and was abandoned in Ethnologue (2009). The family includes the closely related Rotokas and Eivo (Askopan) languages, together with two languages that are more distantly related: Spoken languages Keriaka (Ramopa) Konua (Rapoisi) Rotokas branch Rotokas Askopan There are about 9,000 speakers combined for all four North Bougainville languages.
