Chapare (Spanish:, also called The Chapare, is a rural province in the northern region of Cochabamba Department in central Bolivia. The majority of the territory consists of valley rainforests that surround the area's main waterway, the Chapare River, which is also a tributary of the Amazon River. The provincial capital is Sacaba, 11 km east of Cochabamba. Its principal town is Villa Tunari, a popular tourist destination.
In recent decades, the Chapare province has become a haven for illegal cultivation of the coca plant, which can be used to produce cocaine. This is due to Bolivian drug law, which until recently only permitted the Yungas region to legally grow coca, despite Chapare being a historical area for growth due to its fertility.
