Władysław Taczanowski (/vwaˈdɨ.swaf ta.t͡ʂaˈnɔf.skʲi/; 17 March 1819, in Jabłonna, Lublin Voivodeship – 17 January 1890,[note 1] in Warsaw) was a Polish zoologist and collector of natural history who explored the Russian Far East and northern Africa.
He then joined government service and served on special missions of the governor of Radom.
In 1865 he joined Benedict Dybowski and Victor Godlewski on expeditions to Eastern Russia.
Taczanowski took part in an expedition to Algeria with Antoni S. Waga (1866–67) and wrote several significant studies including Birds of Poland (1882) and Ornithology of Peru (1884-86).
From 1875 he continued to receive specimens from South America after Jean Stolzmann replaced Jelski.
