Moritz Franz Kasimir von Wobersnow (5 March 1708 in Kamissow (Kamosowo)–23 July 1759 at Kay) was a Prussian major general of infantry and a general adjutant of Frederick the Great. He died at the Battle of Kay; a lifelong friend of the King, his name is included on the Equestrian statue of Frederick the Great.
Moritz Franz Kasimir came from the old Pomeranian noble family of Wobersnow. He was a son of Moritz Georg von Wobersnow (1677–1759), heredity lord of Kamissow and his wife, Anne Elisabeth, née Manteuffel, of the House of Popelow.
In 1723, Wobersnow entered the Prussian military service in the infantry regiment "Grumkow" as a fahnenjunker. With Crown Prince Frederick, he transferred to the regiment Moulin, where he remained for the remainder of the reign of Frederick William II and for the first seven years of Frederick's reign, through the War of Austrian Succession. He was promoted to major in 1747. In August 1751, he received for his service a prebendary to the cathedral in Minden, which gave him a regular income. In March 1752 he was promoted to lieutenant colonel and appointed to the adjutant to the king. He was also given control of the light Jaeger Corps. He also accompanied the king to his campaign to Saxony.
He was wounded in the Battle of Prague, but soon recovered to fight at the battles of Rossbach and Leuthen. Frederick sent him and his light troops to support Christoph von Dohna against the Russians. In August 1758 he fought in the Battle of Zorndorf and helped to expel the Russians from Landsberg an der Warthe (Gorzów Wielkopolski) in September.
