The Bang Lang Dam (Thai: เขื่อนบางลาง, RTGS: Khuean Bang Lang, pronounced [kʰɯ̀a̯n bāːŋ lāːŋ]), also known as the Pattani Dam (เขื่อนปัตตานี, RTGS: Khuean Pattani, pronounced [kʰɯ̀a̯n pàt.tāː.nīː]), is a multi-purpose hydroelectric dam in the Bannang Sata District of Yala Province, Thailand. It was the first multi-purpose dam developed in Thailand's southern region. The dam impounds the Pattani River, creating the Bang Lang Reservoir. The dam and its accompanying power plant were developed as part of the Pattani Project.
