Konstantin Vout (1866–1956) was a Soviet violinist, conductor, military bandmaster, and music educator. He graduated from the Kyiv Music School, where he studied with the Czech violinist, composer, and teacher Otakar Ševčík.

From 1895 to 1902, he taught wind instruments at the Kyiv Pechersk Gymnasium. Beginning in the 1902–03 academic year, he taught music at the Kyiv Theological Seminary, and from 1903 he taught music at the Kyiv Cadet Corps, probably also serving as its bandmaster. In 1904 he taught violin at the Mykola Lysenko Music and Drama School in Kyiv.
