Alessio Issupoff (1889–1957) was a Russian and Soviet painter known for his landscape paintings, portraits, and genre scenes. Born as Aleksej Vladimirovich Isupov in Vyatka (present-day Kirov), Issupoff became a prominent figure in both Russian and Italian art circles, achieving significant recognition at the Venice Biennale in 1930. His artistic career spanned from early twentieth-century Russia through the Soviet period and culminated in a prolific emigration to Italy, where he spent the latter half of his life.
