Talysh (also Talishi, Taleshi or Talyshi) are an Iranian ethnic group indigenous to a region shared between Azerbaijan and Iran which spans the South Caucasus and the southwestern shore of the Caspian Sea. They speak the Talysh language, one of the Northwestern Iranian languages. It is spoken in the northern regions of the Iranian provinces of Gilan and Ardabil and the southern parts of the Republic of Azerbaijan. Northern Talysh (the part in the Republic of Azerbaijan) was historically known as Talish-i Gushtasbi. In Iran there is a Talesh County in Gilan. Anthropologically they belong to the Balkan-Caucasian type of the European race.
