Guy Van Nueten (born Turnhout, Belgium, 25 July 1965) is a Belgian pianist, composer and producer.

Van Nueten had piano lessons as a child and underwent some classical training on the instrument, but his musical career took off in pop and rock: he was a member of Belgian indie band, The Sands in the 1990s, after which he enrolled at the conservatory/music academy to study piano, composing and harmony.

Van Nueten composes, performs and records (neo-)classical piano music, but has also composed film scores. Meanwhile, he never lost touch with the world of pop and rock, playing with and composing for Belgian indie/rock bands such as dEUS, Admiral Freebee, Zita Swoon, Magnus and DAAN.
