The Arapesh languages are several closely related Torricelli languages of the 32,000 Arapesh people of Papua New Guinea.

They are among the better-studied of Papuan languages and are most distinctive in their gender systems, which contain up to thirteen genders (noun classes) with noun-phrase concordance. Mufian, for example, has 17 noun classes for count nouns plus two extra noun classes, i.e. proper names and place names. (See that article for examples.)
