Western Mansi is an Uralic language that was described as "probably extinct" in 1988. Although the last speaker is not known, none existed by the end of the 20th century.

The language had strong Russian and Komi influences and considerable dialect differences.

Varieties Western Mansi was noted to be fractured in numerous divergent dialects, most of which were only poorly documented. The earliest linguistic descriptions were based on fieldwork by Antal Reguly in the 1840s and August Ahlqvist in the 1850s. Two varieties were studied by Bernát Munkácsi in 1888 to 1889 and eight varieties, divided in five dialects, were distinguished by Artturi Kannisto, who studied the Mansi from 1901 to 1906. The Pelym dialect is the best-known, studied by Ahlqvist, Munkácsi and Kannisto. Descriptions based on their materials have been given also by Honti and Eichinger. The Middle Lozva dialect was recorded by Reguly and Munkaćsi. By Kannisto's time, only one speaker remained. The Upper Lozva dialect, recorded by Kannisto. The North Vagilsk dialect, recorded by Kannisto, was at the time spoken in three villages, each with their own slight differences. The South Vagilsk dialect, recorded by Kannisto.

Several early wordlists were collected from multiple additional locations in the 18th century. These dialects' precise relationship to the better-known Western Mansi varieties remains unknown. Varieties west of the Urals were recorded along the Vishera (at Cherdyn and Ust-UlsDictionary of Ust'-Uls dialect of Mansi language (Cyrillic), collected by major Karpin and complied by M.A.Castren in XVIII cent. ) and near Solikamsk. Varieties east of the Urals further south are known from along the Southern Sosva and central Tura near Verkhoturye. A wordlist of unknown precise provenance was used by Strahlenberg.

Long arises mostly from earlier *iɣ or *ē adjacent to palatalized consonants. It was rare at Pelym, where these combinations remain, e.g. jiγ 'night', ēť 'evening', in other dialects jī, īť.

All varieties had at least one opening diphthong, continuing Proto-Mansi *ǟ, in most dialects back labial: Pelym and Middle Lozva (ɔå), South Vagilsk (oå), Lower Lozva . In North Vagilsk, this was front (üɔ̈).

In Kannisto's records, short was realized as open-mid or in the Pelym and Lower Lozva dialects; long as Pelym , Lower Lozva .
