Anatoly Nikolayevich Alexandrov (May 25, 1888 [O.S. May 13], Moscow – April 16, 1982, Moscow) was a Soviet and Russian composer of works for piano and for other instruments, and pianist. His initial works had a mystical element, but he downplayed this to better fit socialist realism. He led a somewhat retiring life, but received several honors.

Alexandrov was the son of a Professor of Tomsk State University. He attended the Moscow Conservatory (which he left in 1915), where he was a pupil of Nikolai Zhilyayev, Sergei Taneyev and Sergei Vasilenko (theory), Alexander Ilyinsky (composition) and Konstantin Igumnov (pianoforte). His early music revealed the influence of Nikolai Medtner and Alexander Scriabin. He was appointed Professor at the Moscow Conservatory in 1923. Viktor Belyaev, Alexandrov's first biographer, wrote in 1926: "If Myaskovsky is a thinker, and Feinberg a psychologist, then Alexandrov is, before anything else, a poet." Alexandrov was also a strong proponent of Stanchinsky and edited much of his compositions for publication.
