The Murovdag (also spelled as Murovdagh, Azerbaijani: Murovdağ) or Mrav is the highest mountain range in the Lesser Caucasus. The range is about 70 kilometres (43 mi) long, and Gamish Mountain is its highest peak at 3,724 metres (12,218 ft). It is made up mainly of Jurassic, Cretaceous and Paleogene rocks.

The Murovdag ridge extends north from Hinaldag Peak through Gamish (or Gomshasar) Mountain. The northeastern slope features a group of scenic lakes, including Göygöl near the northern slope. The Karabakh Plateau extends from the south of Murovdag. Fir and spruce forests are spread as far southeast as the Murovdag. The summer mountain pastures of Murovdag were traditionally used by Azerbaijani and Armenian shepherds.

The mountain ridge forms the northern part of the line of control separating the unrecognized Nagorno-Karabakh Republic from Azerbaijan. Its southern slopes run through the Martakert region of Nagorno-Karabakh.
