Yana "Yanka" Stanislavovna Dyagileva (Russian: Янка Станиславовна Дягилева; 4 September 1966 – c. 9 May 1991) was a Russian poet and singer-songwriter and one of the most popular figures of her time in Russia's underground punk scene. She both played solo and performed with others, including Yegor Letov and bands Grazhdanskaya Oborona and Velikiye Oktyabri ("Great Octobers"). Dyagileva was greatly influenced by Letov and Alexander Bashlachev, who were her friends. Her songs explored themes of desperation and depression, punk-style nihilism, and folk-like lamentations.
