The Lesser Caucasus or Lesser Caucasus Mountains, also called Caucasus Minor, is the second of the two main ranges of the Caucasus Mountains, of length about 600 km (370 mi). The western portion of the Lesser Caucasus overlaps and converges with east Turkey and northwest Iran. It runs parallel to the Greater Caucasus, traversing through the Armenian highlands, at a distance averaging about 100 km (62 mi) south from the Likhi Range (Georgia), and limits east Turkey from the north and north-east. It is connected with the Pontic range and separated from it by the Kolkhida Lowland (Georgia) in the west and Kura-Aras Lowland (Azerbaijan) in the east.
