Waskia (Vaskia, Woskia) is a Papuan language of Papua New Guinea. It is spoken on half of Karkar Island, and a small part of the shore on the mainland, by 20,000 people; language use is vigorous. The Waskia share their island with speakers of Takia, an Oceanic language which has been restructured under the influence of Waskia, which is the inter-community language. Waskia has been documented extensively by Malcolm Ross and is being further researched by Andrew Pick.
Waskia is spoken in Tokain (), a village in Malas ward, Sumgilbar Rural LLG on the coast of mainland New Guinea, and on Karkar Island, with the island and mainland varieties being lexically divergent from each other.
/á/ can be pronounced as a fricative [ã] when in intervocalic positions.
Below are some Waskia lexical forms compared with Amako and Proto-Northern Adelbert.
