Tariana is an Arawakan language spoken on the Vaupés River in Amazonas State in Brazil. It has about 100 speakers. Since the 19th century Tariana speakers have been switching to Tucano, an unrelated language, which became the lingua franca in the Vaupés region.
Since 1999 there have been efforts to increase the number of Tariana speakers by teaching it in schools. A grammar and dictionary have also been written.
