Estero Del Cepo is a stream located in the Santiago Metropolitan Region of Chile, flowing through the Andean foothills west of the city. It is one of the notable tributary waterways in the area and plays a meaningful role in the local watershed. Notably, Estero Del Cepo is recognized as one of the headwater sources of the Río Molina — joining with the Estero Las Tinajas to form the Río Molina at their confluence. This origin point gives the stream its significance both hydrologically and from an angling perspective, as the Río Molina extends approximately 20 kilometers from that confluence downstream to its union with the Río San Francisco.
