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.

His poor relationship with the Imperial generalissimo Albrecht von Wallenstein frustrated his plan of becoming the supreme commander of the League's forces.

[1] At the outbreak of the Thirty Years' War, Scharffenstein served in the army of the Bishopric of Worms, which was part of the armed forces of the Catholic League.

Between 1621 and 1623, he fought under Johann Tserclaes, Count of Tilly against the remnants of the rebel forces headed by Ernst von Mansfeld, Christian the Younger of Brunswick and Georg Friedrich, Margrave of Baden-Durlach in the Palatinate campaign.

After the conclusion of the campaign he joined the ranks of the Holy Roman army, departing for the Netherlands where he participated in Spinola's Siege of Breda in 1624.

Not wanting to strain his relationship with the Holy Roman Emperor Ferdinand II by whose grace he received estates in Bohemia, Scharffenstein left the French army shortly before the two states fought in the War of the Mantuan Succession.

Scharffenstein was then appointed to the position of the garrison commander of the Landsberg an der Warthe, repealing a Swedish assault on the city in January 1631.
