Kaitag (Kaitag: Хайдакьан кув [χɑjdɑqʼɑn kʰuβ]; also Kaidak, Karakaitak, Karkaidak, Qaidaqlan) is a Northeast Caucasian language spoken in Dagestan, Russia.

The Routledge Ethnographic Handbook (2017) divided Kaitag into two dialects: northern (Magalis-Kaitak) and southern (Karakaitak).

[4] Consonants form by series of voiced, aspirated, fortis, ejective, and labialized variants.

The letters of the alphabet are (with their pronunciation given below in IPA transcription): [ɑ]~[a] [æ] [b] [β] [g] [gʷ] [ʁ] [ʁʷ] [h] [hʷ] [d] [ɛ]~[e] [ʒ] [ʒʷ] [z] [ɪ]~[i] [j] [kʰ] [kʷʰ] [kː] [kʷː] [kʼ] [kʷʼ] [qʰ] [qʷʰ] [qː] [qʷː] [qʼ] [qʷʼ] [l] [m] [n] [pʰ] [pː] [pʼ] [s] [sː] [tʰ] [tː] [tʼ] [u] [χ] [χʷ] [χː] [χʷː] [ç] [çʷ] [çː] [çʷː] [t͡sʰ] [t͡sː] [t͡sʼ] [t͡ʃʰ] [t͡ʃʷʰ] [t͡ʃː] [t͡ʃʷː] [t͡ʃʼ] [t͡ʃʷʼ] [ʃ] [ʃʷ] [ʃː] [ʃʷː] [ʔ] Most of Kaitag's vocabulary stems from proto-Northeast-Caucasian roots.
