The Berd (Russian: Бердь) is a river in Russia, a right tributary of the Ob.
The Berd begins on the western slopes of the Salair ridge, flows 30km (20miles) in Altai Krai territory and the rest in Novosibirsk Oblast. The river empties into the Novosibirsk Reservoir, which submerged 40km (30miles) of the original Berd river after construction.
The Berd is 363km (226miles) long and was formerly 416km (258miles) long. Its drainage basin covers 8650km2. The Ik is a tributary flowing into it from the north. Another river flowing into it is the Anfimov Mocheg.
Discharge averages 45.8m3/s. Ice forms on the river in the first weeks of November and breaks apart in mid-April.
Naming, it is thought, is from Turkic languages "Berdi" with the meaning of "given".
Two cities, Berdsk and Iskitim, are along the river.
