The Belaya River (Russian: Бе́лая) is a south-flowing tributary of the Anadyr River in far northeast Siberia. It is formed by the juncture of the Emmyvaam River, which drains Lake Elgygytgyn, from the northwest and the Yurukuveem River, whose major tributary is the Bolshaya Osinovaya, from the north. Its basin is 44,700 square kilometres (17,300 sq mi) and its length is 487 kilometres (303 mi) (Belaya plus Yurukuveem). This river passes through sparsely populated areas of Chukotka. The Belaya River meets the Anadyr River more than 300 kilometres (190 mi) from its mouth in the mid-lower stretch of its course. Below the confluence with the Belaya, the Anadyr separates into multiple smaller channels upriver from where the Tanyurer River meets it.
