Mator or Motor was a Uralic language belonging to the group of Samoyedic languages, extinct since the 1840s. It was spoken in the northern region of the Sayan Mountains in Siberia, close to the Mongolian north border. The speakers of Mator lived in a wide area from the eastern parts of the Minusinsk District (okrug) along the Yenisei River to the region of Lake Baikal. Three dialects of Mator were recorded: Mator proper as well as Taygi and Karagas (occasionally portrayed as separate languages, but their differences are few).
