Cambodia does not recognize same-sex marriage or civil unions, but recognizes a registry program known as the "declaration of family relationship" offering some limited legal rights to same-sex couples. By June 2021, this registry, which can serve as an evidence-based documentation of a relationship, had been introduced to 68 communes. Same-sex marriage has received support from King Norodom Sihamoni and his late father, King Norodom Sihanouk, who expressed support after witnessing same-sex marriages in San Francisco in 2004.
The Constitution of Cambodia defines marriage as the union of "one husband and one wife". In 2023, the government suggested it would look into legalising same-sex marriage.
