Lake Qaraoun (Arabic: بحيرة القرعون‎ / ALA-LC: Buḥayrat al-Qara‘ūn) is an artificial lake or reservoir located in the southern region of the Beqaa Valley, Lebanon. It was created near Qaraoun village in 1959 by building a 61-metre-high (200 ft) concrete-faced rockfill dam (the largest dam in Lebanon) in the middle reaches of the Litani River (longest river in Lebanon).
