Kremenchuk (; ) is an industrial city in central Ukraine which stands on the banks of the Dnipro River. The city serves as the administrative center of the Kremenchuk Raion (district) in Poltava Oblast (province). Its population is approximately Although not as large as some other oblast centers, Kremenchuk has a large industrial center in Ukraine and Eastern Europe. A KrAZ truck plant, the Kremenchuk Oil Refinery of Ukrtatnafta, the Kriukiv Railway Car Building Works, and Kremenchuk Hydroelectric Power Plant, in nearby Svitlovodsk, are located in or near Kremenchuk. Highway M22 crosses the Dnieper over the dam of the power plant. Originally established on the left bank, Kremenchuk eventually incorporated the city of on the right bank. The Kriukiv Railway Car Building Works is one of the oldest railway-repair and rail-car-building factories in Eastern Europe, dating from 1869.
