Pavel Nikolayevich Filonov (Russian: Па́вел Никола́евич Фило́нов) (January 8, 1883 – December 3, 1941) was a Russian avant-garde painter, art theorist, and poet.
Filonov was born in Moscow on January 8, 1883 (Gregorian calendar) or December 27, 1882 (Julian calendar). In 1897, he moved to St. Petersburg where he took art lessons. In 1908, he entered St. Petersburg Academy of Arts, from which he was expelled in 1910. In 1910–1914, he took part in the arts group Soyuz Molodyozhi created by artists Elena Guro and Mikhail Matyushin. In 1912, he wrote the article The Canon and the Law, in which he formulated the principles of analytical realism, or "anti-Cubism". According to Filonov, Cubism represents objects using elements of their surface geometry but "analytical realists" should represent objects using elements of their inner soul. He was faithful to these principles for the remainder of his life.

In the autumn of 1916, he enlisted for service in World War I and served on the Romanian front. Filonov participated actively in the Russian Revolution of 1917 and served as the Chairman of the Revolutionary War Committee of Dunay region. In 1919, he exhibited in the First Free Exhibit of Artists of All Trends at the Hermitage. In 1923, he became a professor of St. Petersburg Academy of Arts and a member of the Institute for Artistic Culture (INKhUK). He organized a large arts school of Masters of Analytical Realism (over seventy artists). Their work influenced suprematism and expressionism. In 1929, a large retrospective exhibition of Filonov art was planned at the Russian Museum; however, the Soviet government forbade the exhibition from going forward. From 1932 onward, Filonov literally starved but still refused to sell his works to private collectors. He wanted to give all his works to the Russian Museum as a gift so as to start a Museum of Analytical Realism. He died of starvation on December 3, 1941 during the Nazi Siege of Leningrad.
