Northern Altai or Northern Altay is a collective name for several tribal moribund Turkic dialects spoken in the Altai Republic of Russia. Though traditionally considered one language, Southern Altai and the Northern varieties are not fully mutually intelligible. Written Altai is based on Southern Altai, and is rejected by Northern Altai children.
Northern Altai is written in Cyrillic. In 2006, in the Altay kray, an alphabet was created for the Kumandin variety.
