Karl Binz (1 July 1832 – 11 January 1913) was a German physician and pharmacologist born in Bernkastel. He is known for his investigations on the pharmacological properties and effects of quinine. He studied at the Universities of Würzburg and Bonn, later working at the University of Berlin in the pathological institute of Rudolf Virchow (1821–1902) and at the clinic of Friedrich Theodor von Frerichs (1819–1885). In 1868 he became an associate professor at Bonn, and several years later founded its pharmacological institute (1873). In 1885/86 he was university rector. During the Austro-Prussian War (1866) and Franco-Prussian War (1870–71) he served as a staff physician.
