Nikolay Alexandrovich Milyutin, alternatively transliterated as Miliutin (Russian: Николай Александрович Милютин, December 21 [O.S. December 8] 1889 – October 4, 1942) was a Russian trade union and Bolshevik activist, participant in the October Revolution in Petrograd. After the revolution Milyutin held various executive appointments in Communist Russia related to social security, central planning and finance; reaching that of Commissar of Finance of the RSFSR in 1924–1929. Milyutin is, however, remembered as an urban planner and an amateur architect, author of Sotsgorod concept, and as the editor of Sovetskaya arkhitektura magazine in 1931–1934.
Milyutin was born in Saint Petersburg; his grandfather was a port stevedore, his father a fisherman and fishmonger who also attempted to return to farming and work in the port; after Nikolay's birth he was injured at work and lived the remainder of his life on a disability pension, then already in place in Russian Empire. Despite father's wishes, teenager Nikolay was not inclined to business, rather, he tried to get an education and at the same time was involved in politics. Around 1904 he made contacts with socialist democrats; he took part in the Bloody Sunday rally of January 22 [O.S. January 9] 1905 and later in the storming of police departments to free up political detainees.
