Johannes de Cleve (c. 1529 – 14 July 1582) was a composer active at the court of Ferdinand I and Charles II. He was presumably born in the Duchy of Cleves, and recruited into the court as a choirboy in the same way as Lassus and many others. He was originally a singer in Ferdinand's chapel in Vienna, but when Charles II organized a new chapel in Graz in 1564, he appointed de Cleve as the first Kapellmeister in Graz.
