Bakhtegan Lake (Persian: دریاچۀ بختگان) was a salt lake in Fars province, southern Iran, about 160 km (99 mi) east of Shiraz and 15 km (9.3 mi) west of the town of Neyriz.

With a surface area of 3,500 square kilometres (1,400 sq mi), Bakhtegan was Iran's second-largest lake.

Despite being naturally segregated by narrow strips of land, they used to join to form a single lake during years of heavy rainfall.

[3] The lakes became completely dry from 2008 through 2010 and the ecosystem has suffered adverse effects.
