Hans Wehr (; 5 July 1909, Leipzig – 24 May 1981, Münster) was a German Arabist. A professor at the University of Münster from 1957–1974, he published the Arabisches Wörterbuch (1952), which was later published in an English edition as A Dictionary of Modern Written Arabic, edited by J Milton Cowan. Today, the work is regarded as the standard scholarly dictionary of Arabic for English-speaking students and scholars of the language. For the dictionary Wehr created a transliteration scheme to represent the Arabic alphabet. The latest edition of the dictionary was published in 1995 and is Arabic–German only.
