Junín is a town in Mendoza Province, Argentina. It serves as the head town of Junín Department, the administrative district that surrounds it.
The town is located in the northern part of Mendoza Province, within the Cuyo region of west-central Argentina. As the seat of its department, Junín functions as a local administrative center for the surrounding area.
Junín shares its name with several other places in Argentina and elsewhere, but it is distinct from the better-known city of Junín in Buenos Aires Province. The Mendoza town is one of the department's principal settlements and lies within Mendoza's broader wine-producing region.
