The Austro-Hungarian wolf,[1] also called the reed wolf,[1] common reed wolf,[1] grey reed wolf[1] or Hungarian reed wolf[2] (Hungarian: nádifarkas, German: Rohrwolf), is a wolf or wolf-like animal that is thought to have once inhabited present-day Hungary (possibly also present-day Slovakia) and eastern present-day Austria.

It is generally assumed to have gone extinct before 1900 or in the early 20th century.

The status of the reed wolf is uncertain, as there are few records and no uncontroversial remains.

It could have been: Some of the alleged reed wolves were (primarily in the 20th century) identified as wolves (Canis lupus) or as domestic dogs (Canis lupus f. familiaris/ Canis familiaris), therefore reed wolves are currently usually preferably considered to have been some form of Canis lupus.

It is also possible that the reed wolf was a combination of all the previous possibilities, i.e. some of the reed wolves were actually part of Canis lupus, some were part of Canis aureus, and some were dogs.
