Johann Philipp Kratz von Scharffenstein (1585 – 26 July 1635) was a German nobleman and field marshal, who fought during the course of the Thirty Years' War. He served with distinction in forces of both the Catholic League and Holy Roman Empire. His poor relationship with the Imperial generalissimo Albrecht von Wallenstein frustrated his plan of becoming the supreme commander of the League's forces. Embittered by this he defected to Sweden, where he attained the rank of field marshal. He was captured at the Battle of Nördlingen in 1634 and executed for treason a year later.
