The Lezgians (Lezgian: лезгияр, лекьер, lezgiyar, Russian: лезгины, lezginy; also called Lezgins, Lezgi, Lezgis, Lezgs, Lezgin) are a Lezgic ethnic group native predominantly in Lezgia located in southern Dagestan and northeastern Azerbaijan and who speak the Lezgian language.
The origin of the ethnonym Lezgin requires further research. Nevertheless, most researchers attribute the derivation of Lezgi to be from the ancient Legi and early medieval Lakzi.
Modern-day Lezgins speak Northeast Caucasian languages that have been spoken in the region before the introduction of Indo-European languages. They are closely related, both culturally and linguistically, to the Aghuls of southern Dagestan and, somewhat more distantly, to the Tsakhurs, Rutuls, and Tabasarans (the northern neighbors of the Lezgins). Also related, albeit more distantly, are the numerically small Jek, Kryts, Shahdagh, Budukh, and Khinalug peoples of northern Azerbaijan. These groups, together with the Lezgins, form the Samur branch of the indigenous Lezgic peoples.
