The White Sea–Baltic Canal (Russian: Беломо́рско-Балти́йский кана́л, romanized: Belomórsko-Baltíyskiy kanál), often abbreviated to White Sea Canal (Belomorkanal), is a man-made ship canal in Russia. Opening on 2 August 1933, it connects the White Sea, in the Arctic Ocean, with Lake Onega, which is further connected to the Baltic Sea. Until 1961, it was called by its original name: the Stalin White Sea–Baltic Canal (Belomorsko-Baltiyskiy Kanal imeni Stalina).
The canal was constructed by forced labor of gulag inmates. Beginning and ending with a labor force of 126,000, between 12,000 and 25,000 laborers died according to official records, while Anne Applebaum's estimate is 25,000 deaths.
