Vladimir Mikhailovich Zenzinov (Russian: Влади́мир Миха́йлович Зензи́нов; historically, his surname was also transcribed as Sensinoff:[1] 29 November 1880 — 20 October 1953) was a member of Russia's Socialist-Revolutionary Party, a participant of the First (1905), Second (February 1917), and Third (November 1917) Russian Revolutions, and an author of a number of books.

Arrested at the beginning of the Revolution of 1905 and sentenced to five years banishment in Siberia, he escaped to Western Europe, then returned to St. Petersburg in 1906.

In 1907, he escaped, making his way to Western Europe via Japan, Shanghai, Hong Kong, Singapore, Colombo, and the Suez Canal.

In his memoirs, he tells of some extremely isolated places he visited, such as the village of Russkoye Ustye in the Arctic.

He participated in the February Revolution of 1917, played various roles in the All-Russian Soviet of Workers', Soldiers' and Peasants' Deputies and supported the Provisional Government under A.F.

Arrested during a military coup by Admiral Kolchak in November 1918, Zenzinov was exiled to China.
