The Bagvalal language (Bagulal) is an Avar–Andic language spoken by the Bagvalals in southwestern Dagestan, Russia, along the right bank of the river Andi-Koisu and the surrounding hills, near the Georgian border.

Only the Tlisi dialect has been studied to a certain significance, because of its similarities to the Tindi language.

[citation needed] Bagvalal has been suffering severe problems and is in serious danger of extinction.

[4] Bagvalal has numerous loanwords from such languages as Arabic, Russian, Turkish, and Avar.

Nowadays Bagvalal is only used in family settings, using Avar or Russian for every other area of communication.
