Estero Punitaqui is a river located in the Coquimbo Region of Chile, flowing through the comuna of Punitaqui in the Provincia de Limarí. The stream runs through the town of Punitaqui itself, where it serves as a natural boundary between the older western neighborhoods known as "Pueblo Viejo" and the more central and southern parts of town. The surrounding landscape is characteristic of the semi-arid interior valleys of the Coquimbo Region, shaped by the broader Limarí River watershed — one of the most significant hydrological systems in north-central Chile. The estero sits within a region that includes notable water bodies such as Embalse Recoleta, Embalse La Paloma, and Embalse Cogotí, all of which form part of the larger Limarí basin hydrology. The area around Punitaqui offers natural and cultural attractions that draw visitors to the region, and the stream corridor itself is part of the local landscape that defines the character of this small Andean foothill community.
