The Valkeakoski area is known to have been inhabited since the iron age. More than a thousand years ago, the ridges on the area served as a foundation of the Rapola fort. In the following Middle Ages, the mill town Sääksmäki was the center of the area. However, industrialization towards the end of the 19th century increased the importance of what became the contemporary town of Valkeakoski. The channel of Valkeakoski was opened in 1869, and the first paper mill was completed in 1873, marking the beginning of a continuing tradition of forest industry. The municipality of Sääksmäki, from which the town of Valkeakoski was detached in 1923 was consolidated with Valkeakoski in 1973.
Valkeakoski is notable for the football team FC Haka and also other Haka sections, especially the cross-country skiing section. The "skiing Haka" is one of the most successful skiing teams in Finland.
