Anadyr (Russian: Ана́дырь) is a river in the far northeast Siberia which flows into Anadyr Bay of the Bering Sea and drains much of the interior of Chukotka Autonomous Okrug. Its basin corresponds to the Anadyrsky District of Chukotka.

The Anadyr is 1,146 kilometres (712 mi) long and has a basin of 191,000 square kilometres (74,000 sq mi). It is frozen from October to late May and has a maximum flow in June with the snowmelt. It is navigable in small boats for about 570 kilometres (350 mi) to near Markovo. West of Markovo it is in the Anadyr Highlands (moderate mountains and valleys with a few trees) and east of Markovo it moves into the Anadyr lowlands (very flat treeless tundra with lakes and bogs). The drop from Markovo to the sea is less than 100 feet (30 m).

It rises at about 67°N latitude and 173°E longitude near the headwaters of the Maly Anyuy River, flows southwest receiving the waters of the Yablon and Eropol Rivers, turns east and passes Markvovo and the old site of Anadyrsk, turns north and east and receives the Mayn River from the south, thereby encircling the Lebediny Zakaznik, turns northeast to receive the Belaya River (Chukotka) from the north, turns southeast past the Ust-Tanyurer Zakaznik and receives the Tanyurer River from the north. At Lake Krasnoye, it turns east and flows into the Onemen Bay of the Anadyr Estuary. If the Onemen Bay is considered part of the river, it also receives the Velikaya River (Chukotka) from the south and the Kanchalan River from the north.
