  Chrétien Géofroy Nestler, name also given as Christian Gottfried Nestler (1 March 1778, Strasbourg – 2 October 1832), was an Alsatian botanist and pharmacist.
  
  He studied under Louis Claude Richard in Paris, and in 1806–1810 served as a military pharmacist. He was later a professor of botany to the faculty of medicine at the University of Strasbourg and a chief pharmacist of Strasbourg hospices. In 1816 he was appointed director of the botanical garden at Strasbourg.
  
  As a taxonomist, he described a number of species within the genus Potentilla. The genus Nestlera (family Asteraceae) was named in his honor by Kurt Sprengel.
