Former regions of Armenia

Nairi (, also ''Na-'i-ru''; ) was the Akkadian name for a region inhabited by a particular group (possibly a confederation or league) of tribal principalities in the Armenian Highlands, approximately spanning the area between modern Diyarbakır and Lake Van and the region west of Lake Urmia. Nairi has sometimes been equated with Nihriya, known from Mesopotamian, Hittite, and Urartian sources. However, its co-occurrence with Nihriya within a single text may argue against this.
