Recognition of same-sex unions in Indonesia

Indonesia does not recognise same-sex marriage or civil unions. Marriage laws forbid same-sex marriages and prevent the registration of marriages validly performed abroad.

Historical recognition of same-sex relationships
While there are no records of same-sex marriages as understood from a Western perspective being performed in pre-modern Indonesian cultures, there is evidence for identities and behaviours that may be placed on the LGBT spectrum. A gemblak (ꦒꦼꦩ꧀ꦧ꧀ꦭꦏ꧀, ) is a young Javanese boy kept by an older man (warok, ꦮꦫꦺꦴꦏ꧀) during a period of sexual abstinence or during a heterosexual marriage. The role of the gemblak is closely tied to the Reog dance. Since heterosexual relations with women were regarded as "sapping the strength of the warok", he was allowed to have a young boy, usually between 8 and 16 years of age, to serve him sexually and play a part in the dance. The gemblak sometimes dressed in female clothing, often hailed from a poor rural family and also did domestic chores for the warok. This granted him and his family great social prestige. Today, this custom is strongly discouraged by Muslim religious authorities. The Bugis recognize five separate genders and their culture has traditionally viewed gender as existing on a spectrum, even after conversion to Islam in the 17th century. A bussi (ᨅᨘᨔᨗ, ) is a person who "combines aspects of all genders to form a whole", often acting as a shaman.

Background
Article 1 of the Law No. 1 of 1974 on Marriage (Undang-undang No. 1 Tahun 1994 Tentang Perkawinan) states that marriage is "a physical and spiritual bond between a man and a woman as husband and wife, having the purpose of establishing a happy and lasting family founded on the Belief in God Almighty". Moreover, article 2 states that a marriage is only lawful if it is performed in accordance with the laws of the religions of the respective parties. Meanwhile, Indonesians who have entered into same-sex marriages abroad are not allowed to register their marriage in Indonesia. Additionally, article 34(1) of the Law No. 23 of 2006 on Civil Administration obliges all marriages to be reported to the local authorities within 60 days, and states that "'marriage' can only be performed between a man and a woman". Civil unions (persatuan sipil, ), which would offer a subset of the rights and benefits of marriage, are also not recognized in Indonesia.

The Constitution of Indonesia does not address same-sex marriage explicitly. Article 28B states: "Every person shall have the right to establish a family and to procreate based upon lawful marriage."

Following the legalization of same-sex marriage in the United States in June 2015, proponents, including singer Sherina Munaf, posted celebratory messages on social media and many highlighted their Facebook profile pictures with rainbow filters. This caused political backslash and controversy, with the Minister of Religious Affairs, Lukman Hakim Saifuddin, responding that Indonesia "could not accept" same-sex marriage. Writing for the Indonesia at Melbourne blog, Hendri Yulius wrote, "Under Suharto's New Order, anything that conflicted with the state ideology was considered foreign and a threat to Indonesian moral values and culture. The current generation is living with the legacy of this idea. We were educated to think that culture is fixed, that differences are threatening and alien, never mind the multiple interactions across cultures now possible in a globalised world. The democratic era has also provided more space for religious fundamentalism, which was strongly suppressed by the military regime. The dogmatic interpretations of religion presented by fundamentalist groups reinforce this idea of a static, unchanging culture."

In 2016, police stopped a same-sex marriage ceremony from occurring in Wonosobo, Central Java, arguing that "such a ceremony violated the law and caused discomfort among local residents". In May 2024, pictures shared online of a double marriage ceremony in Wonosobo with both grooms sitting next to each other were misconstrued as being a same-sex marriage. The pictures led to an "explosion" of homophobic rhetoric on social media despite the fact that the ceremony consisted of two sisters marrying their male partners. That same month, a same-sex couple was married in Central Halmahera, North Maluku by having one of the partners dress as a woman. The Regional Office of the Ministry of Religious Affairs requested that the marriage be anulled after discovering that both spouses were men, arguing that the ceremony "violate[d] religious and cultural sharia of the community".

Public opinion
An online polling conducted by the International Lesbian, Gay, Bisexual, Trans and Intersex Association (ILGA) in October 2016 found that 69% respondents were against the legalization of same-sex marriage, while 14% supported and 17% were neutral.

A February–May 2023 Pew Research Center poll showed that 5% of Indonesians supported same-sex marriage (3% "strongly" and 2% "somewhat"), while 92% opposed (88% "strongly" and 4% "somewhat") and 3% were undecided or did not answer. This level of support was the lowest among the six Southeast Asian countries polled, behind Vietnam at 65%, Thailand at 60%, Cambodia at 57%, Singapore at 45%, and Malaysia at 17%.
