MT Varzuga (Russian: Варзуга) was an ice-strengthened product tanker that sailed under the Finnish flag in 1977–2003 and under the Russian flag in 2003–2021. After her modernization in 1993, she became the first merchant ship to be equipped with Azipod, an electric azimuthing propulsion unit developed in Finland in the late 1980s. She was also the first non-Soviet ship to transit the Northern Sea Route.
