Ancash is a department and region in western Peru. It is bordered by the departments of La Libertad on the north, Huánuco and Pasco on the east, Lima on the south, and the Pacific Ocean on the west. Its capital is the city of Huaraz, and its largest city and port is Chimbote. The name of the region originates from the Quechua word anqash, from anqas ('blue') or from anka ('eagle').

Quechua, also called Runasimi in Southern Quechua, is an indigenous language family that originated in central Peru and thereafter spread to other countries of the Andes. Derived from a common ancestral "Proto-Quechua" language, it is today the most widely spoken pre-Columbian language family of the Americas, with the number of speakers estimated at 8–10 million speakers in 2004, and just under 7 million from the most recent census data available up to 2011. Approximately 13.9% of Peruvians speak a Quechua language.
