The Dnieper Hydroelectric Station (Ukrainian: ДніпроГЕС, romanizedDniproHES), also known as the Dnipro Dam, is a hydroelectric power station in the city of Zaporizhzhia, Ukraine. Operated by Ukrhydroenergo, it is the fifth and largest station in the Dnieper reservoir cascade, a series of hydroelectric stations on the Dnieper river that supply power to the Donets–Kryvyi Rih industrial region. Its dam has a length of 760 metres (2,490 ft), a height of 60 metres (200 ft).

The dam elevates the Dnieper river by 37.5 metres (123 ft) and maintains the water level of the Dnieper Reservoir, which has a volume of 3.3 km3 and stretches 129 kilometres (80 mi) upstream to the nearby city of Dnipro. The reservoir's two shipping canals—the disused original one with three staircase locks and a newer one with one staircase lock—allow ships to bypass the dam at its eastern end and sail upstream as far as the Pripyat River. A highway on the dam and bridge over the shipping canals enable vehicles to cross the Dnieper.

The electric station was built by the Soviet Union from 1927 to 1932. After being destroyed during World War II to make it harder for advancing German forces to cross the river and to hamstring their occupation by removing 19% of regional network capacity, it was rebuilt from 1944 to 1950. An expansion built from 1969 to 1980 quadrupled the station's output, with further modernization renovations conducted in the 1990s. In 2024, after being hit by Russian missiles, power output at the Dnieper Hydroelectric Station came to a halt.
