The Kamianske Reservoir (Ukrainian: Кам'янське водосховище, Kamians'ke vodoskhovyshche) is a reservoir located on the lower part of the Dnieper river in the Dnipropetrovsk Oblast of Ukraine, one of five of Dnieper reservoir cascade. Named after the name of the city of Kamianske, the reservoir is mainly used for generating hydroelectric power, transportation, fish farming, and human consumption. Its water level is maintained by the dam of the Middle Dnieper Hydroelectric Power Plant, constructed from 1963 to 1965.
The ports of Kremenchuk and the Dnieper Mineral Enrichment Complex in Horishni Plavni are located on the reservoir, with access being limited when the reservoir freezes over during the winter.
