Miass River (Russian: Миасс, Bashkir: Мейәс) is a river on the eastern side of the Ural Mountains near Chelyabinsk. It flows mainly northeast to join the Iset River which continues northeast to join the north-flowing Tobol River which leads to the Ob River and the Arctic Ocean. Located mostly in Chelyabinsk Oblast and Kurgan Oblast, its length is 658 km and the area of its basin 21,800 km². The Miass River freezes up in late October–November and stays under the ice until April. The cities of Chelyabinsk and Miass are located on the Miass River.

Its headwaters are in the northeast corner of Bashkiria near those of the east-flowing Uy River, the south-flowing Ural River and the Ufa River and Belaya River, both of which lead west to the Volga. It flows about 50 km north past the town of Miass to the Argazi Reservoir, then mostly east to Chelyabinsk and then mostly northeast to meet the Iset River. South of the Miass is the Uy River which flows east to the Tobol and northwest, the Techa River which also flows northeast into the Iset.
