The Bahoruco Mountain Range—Sierra de Bahoruco (or Sierra de Bahoruco) is a mountain range located in the far southwestern region of the Dominican Republic. It is within Pedernales, Independencia, Barahona, and Bahoruco Provinces. A large part of the area is protected within the Sierra de Bahoruco National Park (Parque Nacional Sierra de Bahoruco), also a Biosphere reserve.
Its name is mentioned for the first time by Bartolomé de las Casas in his "Brief History of the Indies", who takes it from the phonetic sound used by the Taino Indians to describe that region.
It is rich in deposits of salt and gypsum, and also has a lagoon in the southern part (Oviedo lagoon) and between this mountain range and the Neiba mountain range is Lake Enriquillo, the largest in the Antilles.
