Mawayana (Mahuayana), also known as Mapidian (Maopidyán), is a moribund Arawakan language of northern South America. It used to be spoken by Mawayana people living in ethnic Wai-wai and Tiriyó villages in Brazil, Guyana and Suriname. As of 2015, the last two speakers of the language are living in Kwamalasamutu. A few rememberers exist who do not use it on a daily basis.
