Same-sex marriage in Finland

Same-sex marriage has been legal in Finland since 1 March 2017. A bill for the legalisation of same-sex marriages was approved by the Finnish Parliament in a vote of 101–90 on 12 December 2014, and signed into law by President Sauli Niinistö on 20 February 2015. Further legislation to harmonise other laws with the legalisation of same-sex marriage was passed in 2016. The law took effect on 1 March 2017. Polling suggests that a majority of Finns support the legal recognition of same-sex marriage. Finland was the last Nordic sovereign state, the twelfth country in Europe and the twentieth in the world to allow same-sex couples to marry nationwide.

From 2002 until 2017, Finland recognized registered partnerships for same-sex couples, which provided the same rights and responsibilities as marriage with the exception of joint adoption rights and the right to a joint last name.
