Oskar Ernst Karl von Sperling (31 January 1814 in Kölleda – 1 May 1872 in Dresden) was a German major general who served during the Baden Revolution and the Second Schleswig, Austro-Prussian, and Franco-Prussian wars.

He then briefly served as company commander in the 32nd Infantry Regiment before returning to the general staff in January 1858, with a promotion to major.

During the Austro-Prussian War he participated in the campaign in Bohemia with the corps being part of the Second Army, commanded by Crown Prince Frederick William of Prussia.

He fought in the Battle of Königgrätz and received the Pour le Mérite on 16 September 1866, on recommendation of General of the Cavalry Louis von Mutius.

The latter wrote "I owe it to the restless activity of Colonel von Sperling and his sensible measures that the troops of the VI Corps intervened in the Battle of Königgrätz at the right time, and his personal prowess on the battlefield itself gives him a just claim to the coveted award, for which I commend him to Your Most High Grace.
