Kelmendi is a historical Albanian tribe (fis) and region in Malësia and eastern Montenegro. It is located in the upper valley of the Cem river and its tributaries in the Accursed Mountains range of the Dinaric Alps. The Vermosh river springs in the village of the same name, which is Albania's northernmost village. Vermosh pours into Lake Plav.

The Albanian tribes form a historical mode of social organization (farefisní) in Albania and the southwestern Balkans characterized by a common culture, often common patrilineal kinship ties tracing back to one progenitor and shared social ties. The fis stands at the center of Albanian organization based on kinship relations, a concept that can be found among southern Albanians also with the term farë.
