The district occupies the lower course of the Onega River and the White Sea coast around the Onega Bay, including the western part of the Onega Peninsula (which it shares with Primorsky District). The waters of the district drain into the Onega and the short rivers of the Onega Bay basin. The main tributaries of the Onega within the district limits are the Kodina and the Kozha Rivers. The exception is the southwestern part of the district which lies in the basin of the Ileksa River, a tributary of Lake Vodlozero, in the Baltic Sea basin. The divide between the Arctic and Atlantic Oceans thus runs through the district. There are many lakes throughout the district; the biggest one being Lake Kozhozero, the source of the Kozha, a left tributary of the Onega. The islands in the Onega Bay are also administered by Onezhsky District. The biggest island of the Onega Bay is Kiy Island.
