The future site of Komsomolsk-on-Amur was conquered by the Mongols in the 13th century, becoming part of the Yuan dynasty. It was later held by the Qing dynasty until the area was ceded to the Russian Empire in the treaty of Aigun in 1858. The village of Permskoye (Пе́рмское) was established on the later site of Komsomolsk in 1860 by migrant peasants from what is now the Perm Krai.

The government of the Russian SFSR announced in 1931 plans to construct a shipyard on the Amur at the present site of Komsomolsk, with construction beginning in 1932. According to official mythology, the town was built using volunteer labor from the Communist youth organization Komsomol (and after 1991, the Russian Communist Youth League), and on that basis receiving the name Komsomolsk. However, the construction of the town was done with the extensive use of forced labour from the concentration camps under the Gulag administration, specifically the Dallag (Far East Camp) complex. The site had been the centre of the system for the Khabarovsk krai. According to Adashova and Kovalev, there was not a single entreprise constructed there in the 1930s or 1940s which had not involved Dallag forced labour, and at least 900 thousand of the mentioned forced labourers passed through the area throughout its existence. The suffix on Amur was added to differentiate from other towns with the same name. It was granted town status in 1933.

By the end of the 1940s, the shipyards along with facilities for other heavy industry had been completed. The city developed into a regional center for industries such as aircraft manufacturing, metallurgy, machinery, oil refining, and shipbuilding. At present, Komsomolsk-on-Amur is the main center for the manufacture of Sukhoi military aircraft and the Sukhoi Superjet airliner. The MiG-15bis and the Lisunov Li-2 were both manufactured in Komsomolsk-on-Amur.

Within the framework of administrative divisions, Komsomolsk-on-Amur serves as the administrative center of Komsomolsky District, even though it is not a part of it. As an administrative division, it is incorporated separately as the city of krai significance of Komsomolsk-na-Amure—an administrative unit with the status equal to that of the districts. As a municipal division, the city of krai significance of Komsomolsk-na-Amure is incorporated as Komsomolsk-na-Amure Urban Okrug. The city is administratively divided into 2 okrugs (previously raion), coinciding with the historical parts: Leninsky (Dzemgi) and Central.

In the Soviet period, the administrative-territorial division of the city was different from the present. In accordance with the Decree of the Presidium of the Supreme Soviet of the RSFSR of 19 October 1943 were formed Lenin, Stalin and Central areas. Stalinsky district included the territory of Railway Amurstali and residential community.

Presidium of the Supreme Soviet of the RSFSR "On the Abolition of the city of Komsomolsk-on-Amur, Khabarovsk Krai" on August 7, 1957 in the district division was abolished, but the decree of March 31, 1972 the Presidium of the Supreme Soviet of the newly divided the city into two districts - Central and Leninsky.
