a river in the Mongolian People’s Republic, a right tributary of the Selenga River. It measures 1,124 km long and drains an area of 132,800 sq km.

The middle Orkhon meanders through a deep valley. After emerging from the mountains, the river widens to 100–150 m. The mean flow rate near the mouth is approximately 120 cu m per sec. In spring there is high water from melting seasonal snow; in summer there are flash floods. The Orkhon is frozen from November through April.
