Recognition of same-sex unions in South Korea

South Korea does not recognise same-sex marriage or civil unions. On 21 February 2023, an appellate court ruled that government health insurance should offer spousal coverage to same-sex couples, the "first legal recognition of social benefits for same-sex couples" in South Korea. This was upheld by the Supreme Court of Korea on 19 July 2024.

Polling suggests that support for the legal recognition of same-sex marriage is declining in South Korea. A 2025 Hankook Research poll showed that 31% of South Koreans supported same-sex marriage, dropping from 36% in 2021. A separate 2025 Gallup Korea survey reported 34% backing legalization compared to 58% opposition, similar to levels of support seen ten years prior.
