Quebrada Alcaparrosa is a stream (quebrada) located in the Coquimbo Region of Chile, situated in the semi-arid landscape characteristic of this part of northern-central Chile. It lies approximately 22 kilometers from the town of Illapel, placing it within a network of seasonal and perennial waterways that drain the Andean foothills and coastal ranges of the region. Like many quebradas in this part of Chile, it flows through terrain shaped by the geology and topography typical of the Coquimbo Region, where watercourses wind through valleys and ravines before eventually contributing to larger river systems. The surrounding area is part of a broader watershed that includes notable nearby waters such as the Río Illapel and Río Chalinga, as well as numerous other quebradas and esteros that define the hydrological character of this semi-arid zone.
