Renko is a former municipality of Finland, located in the Kanta-Häme region in the south of the country. It existed as an independent municipality until it was consolidated with the city of Hämeenlinna on 1 January 2009.
Following that merger, Renko ceased to be a separate administrative unit and became part of Hämeenlinna, the regional centre of Kanta-Häme. The area is therefore now administered as part of a larger municipality rather than as a municipality in its own right.
