Southern or Tavda Mansi is an extinct Uralic language spoken in Russia in the Sverdlovsk Oblast. Its main records come from an area isolated from the other Mansi varieties along the river Tavda.^[4] Around 1900, about 200 speakers existed, but in the 1960s, it was spoken only by a few elderly speakers.^[5] It has since then become extinct. It had strong Tatar lexical influence and displayed several archaisms such as vowel harmony, retention of /æː/ (elsewhere backed to /aː/ or diphthongized), /ɑː/ (elsewhere raised to /oː/)^[6] and /tsʲ/ (elsewhere deaffricated to /sʲ/).^{[citation needed]}

Russian researchers use the term "southern dialect" (Russian: южный диалект) to describe the Tavda language.^[4]

Southern Mansi was formerly spoken along a range to both the west and east of the Ural Mountains. Wordlists of Southern Mansi have been recorded across this area in the 18th century from the towns of Kungur, Verkhnyaya Tura and Verkhoturye and from settlements along the Chusovaya River and Tagil River.^[7] Only the Tavda dialect was met and recorded (from three villages: Janychkova, Chandyri and Gorodok) on the expeditions of the Hungarian linguist Bernát Munkácsi [hu] in 1888–1889 and the Finnish linguist Artturi Kannisto [fi] in 1901–1906. During 1960s expeditions by Hungarian linguists, it, too, was found to be moribund, and is presumed to have become extinct shortly afterwards.
