Montes Caucasus is a rugged range of mountains in the northeastern part of the Moon.

[2] It begins at a gap of level surface that joins the Mare Imbrium to the west with the Mare Serenitatis to the east, and extends in an irregular band to the north-northeast to the western side of the prominent crater Eudoxus.

[3] There are several breaks in the range where nearby lunar mare has intruded into the formation, particularly near the southern tip.

The tallest peaks in this range reach heights of 6 km, undoubtedly providing an expansive view of the surroundings from their tops.

The range was named after the Caucasus Mountains on Earth by the German selenographer Johann H. Mädler.
