Lake Matano (Indonesian:Danau Matano), also known as Matana, is a natural lake in South Sulawesi, Indonesia. With a depth of 590 m (1,940 ft), it is the deepest lake in Indonesia (ranked by maximum depth), and the 10th deepest lake in the world. The surface elevation from mean sea level is only 382 m (1,253 ft), which means that the deepest portion of the lake is below sea level (cryptohollow). It is one of the two major lakes (the other being Lake Towuti) in the Malili Lake system.
