Durmitor (Montenegrin and Serbian Cyrillic: Дурмитор, pronounced [durmǐtɔr] or [dǔrmitɔr]) is a massif located in northwestern Montenegro. It is part of the Dinaric Alps. Its highest peak, Bobotov Kuk, reaches a height of 2,523 meters (8,278 ft).

The massif is limited by the Tara River Canyon on the north, the Piva River Canyon on the west, and by the Komarnica River Canyon on the south. To the east, the Durmitor opens to a 1,500 m (4,921 ft) high plateau, called Jezerska površ (Plateau of Lakes). The Sinjavina mountain is located to the east of the Jezerska površ plateau. The Durmitor is for the most part located in the Žabljak municipality.

The massif gives its name to the national park that comprises it. Durmitor National Park was founded in 1952, and designated as a World Heritage Site in 1980.
