Severodvinsk (; ) is the second-largest city in Arkhangelsk Oblast, Russia. It is located in the oblasts north, in the delta of the Northern Dvina, west of Arkhangelsk, the administrative center and most populous city of the oblast. As of the 2021 Census, the population was 157,213. Due to the presence of important military shipyards (specialising in submarines since the Soviet period), Severodvinsk is an access-restricted town for foreign citizens. A special permit is required.

It was previously known as Sudostroy (until 1938), and Molotovsk (until 1957).

History Pre-20th century Vikings explored the territories around the North Dvina River - part of Bjarmaland - at the start of the second millennium. British and NormanSeverodvinsk—test of strength (Russian), "Pravda Severa" publishing house, 1998 ships came to these places for mining, fur and fishing before the 13th century, but later the climate became colder and access to the northern seas became closed.

The historical records first mention the settlement on the site of modern Severodvinsk in 1419, when the Swedes sailed into the bay and burnt down the Nikolo-Korelsky Monastery that stood by the shore during the Swedish–Novgorodian Wars. Tradition has it that Saint Euphemius, an Orthodox missionary in Karelia, founded this monastery. The abbey stood in ruins until 1471, when two sons of Marfa Boretskaya died in a vicious storm; their bodies were recovered on the beach near the monastery twelve days later. At the urging of Boretskaya, the monastery was restored and her sons were buried there.

On August 24, 1553, a ship of Richard Chancellor reached the salt-mining settlement of Nyonoksa, which is still famous for its traditional wooden architecture. The British sailors visited the Nikolo-Korelsky Monastery, where they were surprised to find a community of "sailors in soutanes (cassocks)" and a pier large enough to accommodate several ships. The main church of this extraordinary establishment was dedicated to Saint Nicholas, the holy patron of sailors; hence, the whole White Sea became known in 16th-century English maps as "St. Nicholas Bay". In late 1613, during the Time of Troubles in Russia, Polish-Lithuanian vagabonds, the Lisowczycy, captured and looted Severodvinsk with the monastery.

The Nikolo-Korelsky Monastery flourished after the establishment of the Muscovy Company, as the bulk of their trade passed through the local harbor. In August 1618 the harbour was visited by John Tradescant the elder, who conducted a survey of an island situated opposite the monastery. This island became known to the British as "Rose Island", because it was there that Tradescant found an exceedingly rare plant which he named "Rosa moscovita" (which is now known as Rosa acicularis) and brought back to London.

The surviving buildings of the monastery were constructed at the close of the Muscovite period. The five-domed cathedral of St. Nicholas was built between 1670 and 1674, preceded by the Assumption church (1664–1667), to which it is joined by a gallery. Several decades later, the walls and towers were built of timber; the Soviets transported the best-preserved of these towers to Kolomenskoye, Moscow, where it still remains.

Modern city Severodvinsk is the second-largest city in the Arkhangelsk Oblast. Its main industry remains defense-related — the construction and repair of submarines at the huge Northern Machine-building Enterprise SEVMASH (), which built the Soviet Union's first nuclear submarine Leninsky Komsomol here in 1957. From 1976 to 1981 Dmitry Donskoy, the world's largest submarine, a Typhoon class boat, was also built here, as later recorded in the Guinness Book of World Records.

In the Soviet period the modern city of Severodvinsk developed from 1936 onwards. Initially dubbed Sudostroy ( - "Boat-build"), it received town status in 1938; from 1938 until 1957 it was named Molotovsk (), after Vyacheslav Molotov (1890-1986). On September 12, 1957, it was renamed Severodvinsk (meaning "Northern Dvina town").

Construction Site 203 aimed to complete the warship-building project and build the city and was driven by the Yagrinlag camp complex (1938-1953) and its thousands of prisoners.

During the Soviet Union's participation in World War II between 1941 and 1945 a significant portion of the materials delivered by the Arctic Convoys to Murmansk and Arkhangelsk were unloaded in Molotovsk (Severodvinsk). For example, the Empire Elgar, a British heavy-lift ship arrived in Arkhangelsk with convoy PQ 16 in May 1942 and subsequently spent eight weeks unloading ships from the ill-fated convoy PQ 17.

A Russian naval-base supports the sea trials of nuclear submarines from the major submarine construction- (64.5817 N, 39.8307 E) and repair-facilities located in the area. In Soviet times, the 17th-century buildings of the Nikolo-Korelsky monastery, located on the territory of the shipyard, were adapted and used for shipbuilding purposes. In recent years, the monastery buildings, specifically the main church, have been restored and re-consecrated. Church-goers attending services have to be shipyard workers or able to obtain a pass to enter the church portion of the shipyard.

Severodvinsk is an access-restricted town for foreign citizens. A special pass is required.

On 8 August 2019, a nuclear accident took place on the Russian Navy's Central Missile Range in Nyonoksa, 30 km to the west from Severodvinsk.
