Huarpe was a small language family of central Argentina that consisted of two closely related languages, traditionally considered dialects, Alyentiyak (Allentiac, Huarpe) and Milykayak (Millcayac).

Kaufman (1994) tentatively linked Huarpe to the Mura-Matanawi languages in a family he called Macro-Warpean. However, he noted that "no systematic study" had been made, so that it is best to consider them independent families. Swadesh and Suárez both connected Huarpe to Macro-Jibaro, a possibility that has yet to be investigated.

Phonology

The two languages had apparently similar sound systems, and were not dissimilar from Spanish, at least from the records we have. Barros (2007) reconstructs the consonants as follows:

	Labial	Alveolar	Palatal	Velar	Glottal
Nasal	m	n	ɲ	ŋ
Plosive	p	t		k
Affricate		ts	tʃ
Fricative		s	ʃ		h
Semivowel	w		j	(ɰ)
Lateral		l	ʎ
Trill		r

Allentiac had at least five vowels, written a, e, i, o, ù. The ù is thought to represent the central vowel ɨ.
