Keeyow Lake (Persian: دریاچه کیو, Lurish: سراو کیاو) is a natural lake in the northwest of Khorramabad in Lorestan Province, Iran. The lake has a seven-hectare area and a depth of 3 to 7 meters. There is an amusement park as well as other recreational facilities next to the lake. It is the only natural city lake in Iran and is a habitat for native and migratory birds and aquatic animals.

This lake was built during the years 1933 -1934. Subsequently, the municipal authorities completed it within a few years with extensive measures and standardized it in its current form. Among these actions was the construction of a tourist guest house and the construction of comfort and recreational facilities such as the game city around the lake.
