The Kott (Kot) language (Russian: Коттский язык) is an extinct Yeniseian language that was formerly spoken in central Siberia by the banks of Mana River, a tributary of the Yenisei river. It became extinct in the 1850s. Some linguists believe the Assan language was a dialect of Kott. Kott was closely related to Ket, still spoken farther north along the Yenisei river.
In 1858, Matthias Castrén published the grammar and dictionary (Versuch einer jenissei-ostjakischen und kottischen Sprachlehre), which included material on the Kott and Ket (Yenisei-Ostyak) languages.
