Harzandi or Harzani (Tati: هرزندی، هرزنی) is a dialect of the Tati language,^[2][3][4][5] spoken in the northern regions of the East Azarbaijan province of Iran. It is strictly an oral language, and a descendant of the Old Azeri language that has long been extinct as a result of the diffusion of Turkish in the area.^[6] Harzandi has many common linguistic features with both Talysh and Zaza and was positioned between the Talysh and Zaza.^[7]

Harzani Tati is considered an endangered language with a little less than 30,000 speakers in present day.^[8] Its speakers principally reside in the rural district of Harzand, particularly in the village known as Galin Qayah. Harzani is also present in the neighboring villages of Babratein and Dash Harzand.^[6]

As of now, Harzani has not been formally recognized by the Islamic Republic of Iran, and thus receives no government support.^[9]

Like other languages and dialects of the Iranian language family, Harzani follows a subject–object–verb (SOV) word order. It has nine vowels, and shares a consonant inventory with Persian. It further exhibits a split-ergative case system: its present tense is structured to follow nominative-accusative patterning, while its past tense follows ergative-absolutive.

One characteristic that distinguishes Harzani from related Northwestern Iranian languages is its change from an intervocalic /d/ to an /r/.^[3] It also has a tendency to lengthen its vowels. For instance, it has the closed vowel /oe/.

Part of Harzani's counting system is as follows:^[10]
