Same-sex marriage in Estonia

Same-sex marriage has been legal in Estonia since 1 January 2024. The government elected in the March 2023 election, led by Prime Minister Kaja Kallas and consisting of the Reform Party, the Social Democrats and Estonia 200, vowed to legalize same-sex marriage. Legislation to open marriage to same-sex couples was introduced to the Riigikogu in May 2023, and was approved in a final reading by 55 votes to 34 on 20 June. It was signed into law by President Alar Karis on 27 June, and took effect on 1 January 2024. Estonia was the first Baltic state, the first post-Soviet state, the twentieth country in Europe, and the 35th in the world to legalise same-sex marriage.

Registered partnerships which provide some of the rights, benefits and obligations of marriage have been available to same-sex couples since 1 January 2016.
