The Sakhalin Tunnel (Russian: Сахалинский тоннель) is an incomplete and currently postponed construction project, which after completion would connect the island of Sakhalin with mainland Russia via a tunnel of approximately 10 kilometres (6.2 mi) under the Nevelskoy Strait (the narrowest part of the Strait of Tartary). On January 16, 2009, it was suggested by the Russian government the link could be completed with a bridge, rather than tunnel.

The concept of a tunnel under the Nevelskoy Strait has existed since the 19th century, although it was never seriously pursued due to economic reasons. Studies into the feasibility of the project were first undertaken by the Soviet Union in the late 1930s, although World War II made progress at this time impossible. Joseph Stalin later announced in 1950 his intention to build a railway link to Sakhalin, either via rail ferry, a causeway, or a tunnel. A decision to construct a tunnel was announced by the Soviet government on May 5, 1950, along with a rail ferry link to serve as a temporary solution. The project was intended primarily to serve a military purpose, allowing better connection between Sakhalin and the mainland for sections of the Red Army stationed on the island.
