The Syas River (Russian: Сясь) is a river in the Lyubytinsky District of Novgorod and Tikhvinsky and Volkhovsky Districts of Leningrad Oblasts, Russia. The Syas River flows from Valdai Hills north into Lake Ladoga. A town of Syasstroy is located at its mouth. It is 260 kilometres (160 mi) long, and the area of its basin 7,330 square kilometres (2,830 sq mi). The largest tributary of the Syas is the Tikhvinka River (right).
The source of the Syas is in the Valday Hills north of the settlement of Nebolchi. The river flows north and enters Leningrad Oblast. It crosses the Tikhvin Range from the south to the north. Further north, it accepts the Tikhvinka from the right and turns west. There it accepts the Lunenka from the left, turns northwest and crosses into Volkhovsky District. The mouth of the Syas is downstream from the city of Syasstroy.
The Syas freezes up in November (sometimes in December or even January) and stays under the ice until April.
During the late Vendel Age and early Viking Age, the Syas River was popular as an alternative route to the Volkhov for penetrating from the Baltic Sea through portages to the Volga River. A fortress of Alaborg was built by the Vikings to guard the approaches to the Syas rapids. The route had declined by the 10th century.
