List of twin towns and sister cities in Finland

This is a list of municipalities in Finland having standing links to local communities in other countries known as "town twinning" (usually in Europe) or "sister cities" (usually in the rest of the world).

Due to Russian invasion of Ukraine in February 2022, many Finnish municipalities have severed ties with their Russian twin towns.
