Map of the Ob River watershed

The Ob River (Russian: Обь; IPA: [opʲ]), also Obi, is a major river in western Siberia, Russia and is the world's seventh-longest river. It forms at the confluence of the Biya and Katun Rivers which have their origins in the Altay Mountains. It is the westernmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Yenisei River and the Lena River).
The Gulf of Ob is the world's longest estuary.
The Ob is known to the Khanty people as the As, Yag, Kolta and Yema; to the Nenets people as the Kolta or Kuay; and to the Siberian Tatars as the Umar or Omass. Possibly from Proto-Indo-Iranian *ap-, "river, water" (compare Persian āb, Tajik ob, and Pashto obə, "water").
The Ob forms 25 km (16 mi) southwest of Biysk in Altai Krai at the confluence of the Biya and Katun rivers. Both these streams have their origin in the Altay Mountains, the Biya issuing from Lake Teletskoye, the Katun, 700 kilometres (430 mi) long, bursting out of a glacier on Mount Byelukha.
