Southern Khanty is a Uralic language, frequently considered a dialect of a unified Khanty language, spoken by 56 people in 2010.

[2] It is considered to be extinct,[1] its speakers having shifted starting in the 18th century to Russian or Siberian Tatar,[3][4] but some speakers of the Kyshikov or Ust-Nazym dialect[5] were found in its former territory.

Speakers of Surgut Khanty have moved into the former territory of the Demyanka dialect.

[6] It was transitional between the Northern Khanty and Eastern Khanty dialect groups, but it is now a distinct language.

These include loss of full front rounded vowels: *üü, *öö, *ɔ̈ɔ̈ > *ii, *ee, *ää (but *ɔ̈ɔ̈ > *oo adjacent to *k, *ŋ),[7] loss of vowel harmony, fricativization of *k to /x/ adjacent to back vowels,[8] and the loss of the *ɣ phoneme.
