Bucalemu is a small coastal settlement in the comuna of Paredones, Provincia Cardenal Caro, O'Higgins Region, sitting where the estero Paredones meets the Pacific Ocean.

The estero travels roughly 15 kilometers westward from its headwaters near the town of Paredones — or about 27 kilometers counting its longest tributary — before emptying into laguna Bucalemu, which lies directly beside the sea at this point.

The village is known for artisanal fishing, a quiet rural character, and its role as the most significant beach destination within the Paredones commune. Its name derives from the Mapudungun words for "large forest."

The beach has been developed with inclusive access infrastructure, enabling visitors with reduced mobility to reach the shoreline during the summer season.
