Valentin Silvestrov (born September 30, 1937 in Kiev) is a Ukrainian composer of contemporary classical music, increasingly regarded as one of the finest composers of his generation.

Silvestrov is perhaps best known for his avant-garde musical style; some, if not most, of his works could be considered neoclassical and modernist. Using traditional tonal and modal techniques, Silvestrov creates a unique and delicate tapestry of dramatic and emotional textures, qualities which Silvestrov suggests are otherwise sacrificed in much of contemporary music.
