Jan van Turnhout (c. 1545 – 1614[1] or 1618[2]) was a composer of the Franco-Flemish School.
In 1577 he was appointed Kapellmeister at St Rumbold's Cathedral in Mechelen.
Around 1586 he got a similar position (maître de chapelle) with Alexander Farnese in Brussels, which he would keep until his death.
He published Il primo libro de madrigali en Sacrarum cantionum.
The latter (Gij meijskens die vander comenscap sijt) was published in 1572 by the Antwerp printer Petrus Phalesius in his anthology of Dutch songs, the Duijtsch musijck boeck.
