Hans Karl von Winterfeldt (April 4, 1707 – September 8, 1757), a Prussian general, serves in the War of the Polish Succession, the War of Austrian Succession, Frederick the Great's Silesian wars and the Seven Years' War.

One of Frederick's trusted confidantes and advisors, he attracts enmity from other courtiers.

Frederick entrusts him with considerable autonomy on the general staff, and Winterfeldt develops the first "modern" program of military intelligence gathering.

He negotiates the Convention of Westminster and receives the Order of the Black Eagle and the Order Pour le Mérite.

He dies from wounds received at Battle of Moys.

His name is included on the Equestrian statue of Frederick the Great.
