Kubachi (alternatively Kubachin) is a language in the Dargin dialect continuum spoken in Dagestan, Russia, by Kubachi people.

[3] It is often considered a divergent dialect of Dargwa, but it has also historically been portrayed as a separate language.

Ethnologue lists it as a separate language.

[2] The glottal stop transcribed here is named rather ambiguously a "glottalic laryngeal" by both sources.[which?]

The original Dargwic phoneme [r] in Kubachi has become [j] or disappeared, lengthening the neighboring vowel.
