George Meissner (19 November 1829 – 30 March 1905) was a German anatomist and physiologist born in Hanover. He studied medicine at the University of Göttingen, where he worked closely with Rudolf Wagner (1806–1864). In 1851 he accompanied Wagner and Theodor Billroth (1829–1894) on an expedition to Trieste, where he performed scientific studies of torpedo fish. In 1852 he earned his doctorate at Göttingen, and was later a university professor at Basel (from 1855), Freiburg (from 1857) and Göttingen (1860–1901).
