Anastasy Andreyevich Vonsyatsky, born on May 30 (June 12) 1898 in Warsaw and died on February 5, 1965 in St. Petersburg, was a Russian émigré politician. He became one of the founders of Russian fascism and led the All-Russian Fascist Organization (VFO). In 1934 and 1935, Vonsyatsky was also one of the leaders of the All-Russian Fascist Party (VFP).

In 1933, he created and headed the VFO, which in 1934 merged with the Russian Fascist Party (RFP), the largest organization among Russian émigrés, founded in the Far East. Together with the General Secretary of the RFP K. V. Rodzaevsky, Vonsyatsky became the leader of the united All-Russian Fascist Party. In 1935, after a split with Rodzaevsky, he again headed the VFO and remained its leader until June 1941. Vonsyatsky maintained contacts with the German-American Alliance, and in June 1942 he was arrested and convicted in the USA on charges of espionage. After his release in 1946, he withdrew from active political life.
