Nikolai Malakhovsky (1892–1942) was a Russian and Soviet composer. He graduated from Petrograd University in 1917 and, in 1925, completed his studies in composition at the Leningrad Conservatory under Maximilian Steinberg. He studied alongside Dmitri Shostakovich.
Malakhovsky worked at the Leningrad Radio Committee and later at the Institute of Art History in Leningrad. He was a member of the Association for Contemporary Music and the Soviet Composers’ Union. He died in Leningrad in 1942. Most of his scores were lost when they burned during the war.
He wrote sonatas, instrumental pieces, romances, and music for theatre, radio, and films. His works included a sonata for trumpet and piano and the unfinished opera The Babylonian Wand, based on a play by Alexander Lunacharsky. His film work included the score for The Sniper (1931). His music is now little known to listeners.
