Eugen von Halácsy, also known as Jenő Halácsy (11 December 1842 in Vienna – 16 December 1913 in Vienna) was an Austrian physician and botanist of Hungarian descent.

In 1865 he obtained his medical doctorate from the University of Vienna, and afterwards served under surgeon Johann von Dumreicher during the Austro-Prussian War (1866). In 1867 he settled as a general practitioner in Vienna.[http://www.biographien.ac.at/oebl/oebl_H/Halacsy_Eugen_1842_1913.xml Halácsy, Eugen von (1842-1913), Botaniker] Österreichisches Biographisches Lexikon und biographische Dokumentation

He specialized in flora of the Balkan peninsula, and on several occasions traveled to Greece, where he worked closely with Theodor von Heldreich, director of the botanical garden in Athens. In 1912 received an honorary doctorate from the University of Athens.
