Ulz River (Mongolian: Улз гол, Russian: Улдза, romanized: Uldza) is a river in Mongolia, which partially flows in Transbaikal, Russia, within the Daursky Nature Reserve. It flows into the Barun-Torey (ru:Барун-Торей) lake.
At about 20 km (12 mi) before the mouth, a branch to the right is split named Teliin Gol (телийн гол) (which until 2013 was dry for many years) which delivers water into the river Шуду-Гол (Shudu Gol), which sinks into the lake Khökh Nuur.
In 2014, around 0.5 million m3 (18 million cu ft) of water was withdrawn from the river for livestock and industrial use.
