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

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.
