Karkkila (Finnish pronunciation: [ˈkɑrkːilɑ]; Swedish: Högfors) is a town and a municipality of Finland.

[5] It was decided to form Pyhäjärvi as an independent parish by a decision of the Imperial Senate in 1861, but the separation did not happen until 1869.

The growth and industrialization of Karkkila has been affected by the now closed narrow-gauge Hyvinkää–Karkkila railway.

Up to the municipal elections in 2012, the Left Alliance had always been the most voted party in Karkkila.

This active town twinning began in 1991 and there are regular events, such as a produce market from each of the other countries and festivals.
