The Sakhalin Tunnel (Russian: Сахалинский тоннель) is an incomplete and currently indefinitely postponed construction project, which after completion would have connected the island of Sakhalin with mainland Russia via a tunnel of approximately 10 kilometres (6 mi) under the Nevelskoy Strait (the narrowest part of the Strait of Tartary).
The construction started under the late Stalinist rule to serve primarily military and settlements purposes, and was abandoned soon after Stalin's death in 1953.
