Lake Qaraoun 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 m-high (200 ft) concrete-faced rockfill dam in the middle reaches of the Litani River. The reservoir has been used for hydropower generation, domestic water supply, and for irrigation of 27,500 ha.

The Beqaa Valley, also transliterated as Bekaa, Biqâ, and Becaa and known in classical antiquity as Coele-Syria, is a fertile valley in eastern Lebanon. It is Lebanon's most important farming region. Industry also flourishes in Beqaa, especially that related to agriculture.
