Pachapaqui is a village in the north of Aquia District in the Bolognesi Province of the Ancash Region, Peru.

It has about a thousand inhabitants, mostly engaged in raising cattle and sheep, and small-scale agriculture.

Due to its altitude it is located in the Suni or Jalca region according to Javier Pulgar Vidal.

It is characterized by heavy rainfall and occurrences of fog that can stay in the valleys all day long.

Now the dominant language is Castilian while Quechua is spoken almost entirely by the elderly due to the recent influx of new residents from the coast who speak only Spanish.
