Cochinoca is a department located in the Jujuy Province, (Argentina).

When the Spanish conquistadors arrived in the region in the third decade of the sixteenth century they found indigenous, casabindos and cochinocas (partially originating from a mixture of likan antai and omaguacas).

These were living in a large zone with abundant mineral resources and from the fifteenth century up to this point have been affected by quechua invaders.

This may account for Cochinoca becoming the most important village in the Puna area of Argentina.

Because of the displacement of the route through the village, the loss of its status as head of the department in favour of Abra Pampa, as well as the east-bound train line and the decrease in minerals, by 1915 its population was reduced to 45 people.
