Arin is an extinct Yeniseian language formerly spoken in Russia by the Arin people along the Yenisei River, predominantly on its left shore, between Yeniseysk and Krasnoyarsk, north of the Minusinsk region. However, it has been suggested that the Arin people had historically occupied a larger geographical range. It became extinct in the 18th century, with the death of Arzamas Loskutov, who was an informant for Gerhard Friedrich Müller in 1731, and for a Cossack adventurer named Ivan Kovrigin in 1735.
It is believed that the term Ar or Ara was used by speakers of Arin to refer to themselves.
