Union of Freethinkers of Finland

The Union of Freethinkers of Finland (Vapaa-ajattelijain Liitto ry, Fritänkarnas Förbund rf) is the largest secularist and freethought organisation in Finland. The organisation supports the rights of those Finns who hold no religious affiliation, and promotes a science-based, rational and critical world view and humanistic ethics.

The organisation was founded in 1937 under the name the Union of Civil Register Associations (Siviilirekisteriläisyhdistysten keskusliitto).

The Tampere section of the organisation created the Eroakirkosta.fi website in 2003, which offers an electronic service for resigning from Finland's state churches.
