Mount Do Baradaran () is a mountain in Qom Province, Iran, on the south-eastern edge of the city of Qom, between the Jamkaran district and the neighbouring Mount Khidr (Kuh-e Khidr). It is formed of twin peaks of nearly equal height and is one of the natural features of Qom that have been entered on Iran's national list of natural heritage.

Name The name "Two Brothers" (, Do Baradaran) refers to the mountain's two adjacent summits, which are of similar size and shape; the eastern summit is slightly the higher of the two.

Geography Mount Do Baradaran lies to the south-east of the city of Qom, close to the Jamkaran Mosque and adjoining Mount Khidr. The geographical database GeoNames records the peak at with an elevation of . Persian-language sources, drawing on OpenStreetMap data, give a somewhat lower figure of about . The mountain has an east–west trending summit ridge created by its two joined peaks.

Geology Iranian sources describe the mountain as a north-eastern continuation of the Zagros ranges, although Qom itself lies within the Central Iranian and Urmia–Dokhtar transitional zone. Surveys have reported numerous fossil deposits of Tertiary age on and around Mount Do Baradaran, the sediments of an ancient sea, which give the area paleontological significance; for this reason its protection, including a proposed geopark, has been advocated.

Conservation Mount Do Baradaran was registered on Iran's national natural-heritage list together with a number of other natural features of Qom Province, among them the Qom salt dome and several ancient trees.

Mountaineering In spite of its modest height, the mountain is considered technically demanding to climb, with steep and locally overhanging rock faces. Its southern face in particular is regarded as dangerous and has been the scene of climbing accidents, so ascents are treated as technical mountaineering requiring ropes and equipment.
