Huaylas Quechua is an Ancash Quechua dialect spoken in the Callejón de Huaylas and in the western slope of the Cordillera Negra.

The main peculiarities of this variety are phonetic. In Quechua Ancash-Huailas a phenomenon of monophthongation of syllables with semiconsonants in coda is present: "aw" is often pronounced as [oː] elongated, likewise "ay" as [eː]. For example, awmi is pronounced [oːmi], chawpi (center) [t͡ʃoːpi] and aywan (walks) as [eːwan]. In grammatical terms, Huaylas lacks the suffix -ski.
