Sevmorput (Севморпуть) is a Russian nuclear-powered cargo ship with ice breaking abilities, one of only four nuclear-powered cargo ships ever built, and the only one still operating under nuclear power, with the others having been retired or been converted to diesel propulsion. The Sevmorput, as a type of cargo ship, is classified as a Lighter Aboard Ship, transporting lighters and ISO standard containers in specially provided cells in the bilge and on the main deck. It was constructed in Kerch, Ukraine at the Zaliv shipbuilding plant. The ship was completed in 1988.

The name of the vessel, Sevmorput, is a Russian abbreviation of Severny Morskoy Put (Северный Морской Путь), i.e. the Northern Sea Route.

Earlier owned and operated by the Murmansk Shipping Company, Sevmorput was transferred to Rosatom in August 2008.

The supposed conversion of the Sevmorput into an oil drilling vessel, as of August 2007, expected to take only 18 months , probably hasn't been started, and it's not clear if the conversion will happen at all. If converted, it may no longer be a ship, but simply an unpowered ship-like oil drilling vessel.
