Geert van Turnhout (French: Gérard de Turnhout; c. 1520 – 15 September 1580) was a Flemish composer, who became master of the Flemish chapel (capilla flamenca) in Spain.
He had a younger brother, also a composer, Jan van Turnhout.
[1] Turnhout was employed first at Antwerp, then at the Church of St Gummarus, Lier, Belgium, (maître de chapelle 1559), then in 1562 back to the Cathedral of Our Lady (Antwerp) where he was made maître de chant in 1563.
Turnhout arrived in Madrid with a group of singers from the Low Countries.
He remained there until his death, when he was succeeded by George de La Hèle.
