The Pyasina River originates in Lake Pyasino and flows into the Pyasino Gulf of the Kara Sea. There are more than 60,000 lakes in the basin of the Pyasina covering a total area of 10,450 square kilometres (4,030 sq mi). The river freezes up in late September or early October and stays under the ice until June. It is connected to the Chetyrekh River through the Starica right tributary.

The Dvina merchant Kondratiy Kurochkin reached the mouth of the Pyasina in 1610. In 1614, an ostrog was built on the river to collect yasak from the natives. In 1935, before the Dudinka-Norilsk railway had been built, the Pyasina River and Lake Pyasino were used to deliver cargo to the site of the future city of Norilsk.
