Harzani (correct form: harzandi) is a modern Northwestern Iranian language spoken in the north of the Iranian province of East Azarbaijan, around the village of Harzand . It is considered a dialect of the Tati language and is closely related to the Talishi (Taleshi) and Karingani dialects.

The major difference between Harzandi and other related dialects is its tendency to use longer vowels. It also has the close vowel 'oe' which is absent in other Tati dialects. Like other Tati dialects, Harzandi tends to change the Iranian voiced dental 'd' into a liquid r, e.g. shuran (to go) for shudan (c.f. Middle Persian shudan-)

Some Harzandi words: oev (öv)= Water; voer= Wind, hoev= Sister, isbaa= Dog (c.f. Rus. spaka).
