Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and herpetologist.
Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum of Berlin from 1874 to 1921.
He was an expert on African birds, making a collecting expedition to West Africa in 1872 and 1873, and writing Die Vögel Afrikas (1900–05).
He was also an expert on parrots, describing all species then known in his book Vogelbilder aus Fernen Zonen: Abbildungen und Beschreibungen der Papageien (illustrated by Gustav Mützel, 1839–1893).
Reichenow is known for his classification of birds into six groups, described, as "shortwings, swimmers, stiltbirds, skinbills, yoketoes, and treebirds".
