Caseros is a city in Buenos Aires Province, Argentina. It is the head town of the Tres de Febrero Partido, a district that forms part of the Greater Buenos Aires urban conurbation surrounding the national capital.
Its location within Greater Buenos Aires places Caseros in one of the most densely populated areas of Argentina, closely linked to the metropolitan core rather than standing as a separate, distant settlement. As the administrative seat of Tres de Febrero Partido, it hosts the local government functions for that district.
Beyond its role as a partido head town and its position in the Buenos Aires metropolitan area, Caseros is defined chiefly by these administrative and geographic characteristics.
