Onega River (Russian: Онега) is a river in the Arkhangelsk Oblast in Russia.
The length of the Onega is 416 km. The area of its basin is 56,900 sq km. The river originates in the Lake Lacha and flows into the Onega Bay, White Sea Southwest of Arkhangelsk. It splits into the Big Onega and Little Onega Rivers 75 km from its estuary, but then these branches join again, forming a big flat island.
It freezes up in late October - early December and stays under the ice until mid-April - May.
The cities of Kargopol and Onega are located on the Onega River.
