Same-sex marriage has been legal in Chile since 10 March 2022. The path to legalization began in June 2021 when President Sebastián Piñera announced his administration's intention to sponsor a bill for this cause. The Chilean Senate passed the legislation on 21 July 2021, followed by the Chamber of Deputies on 23 November 2021. Due to disagreements between the two chambers of the National Congress on certain aspects of the bill, a mixed commission was formed to resolve these issues. A unified version of the bill was approved on 7 December 2021. President Piñera signed it into law on 9 December, and it was published in the country's official gazette on 10 December. The law took effect 90 days later, and the first same-sex marriages occurred on 10 March 2022. Chile was the sixth country in South America, the seventh in Latin America and the 29th in the world to legalize same-sex marriage.
Before this, Chile recognized same-sex couples through civil unions, known in Spanish as acuerdo de unión civil (AUC), which were available to all couples regardless of sexual orientation and provided some, but not all, of the rights of marriage. The first civil unions were registered on 22 October 2015.

## Civil unions
### Bachelet's first presidency

In the January 2006 presidential campaign, both major candidates, center-left Michelle Bachelet and center-right Sebastián Piñera, voiced their support for civil unions, but the Catholic Church and many members of the National Congress were opposed.
In October 2009, a civil union bill was introduced to the National Congress, but it failed to pass.

### Piñera's first presidency

During his run-up to the presidency in 2009, Piñera vowed to end discrimination based on sexual orientation and included a same-sex couple in one of his televised campaign ads.
In June 2010, Senator Andrés Allamand (National Renewal) submitted a bill to Congress to permit a "Common Life Agreement" (Spanish: Acuerdo de Vida en Común), which would have been open to both different-sex and same-sex couples. On 3 August 2010, Senator Fulvio Rossi (Socialist Party) introduced a bill to legalize same-sex marriage. During the first week of September 2010, several senators backing the marriage bill said they would withdraw their support after talks with members of the Evangelical Church, and instead announced support for the civil union bill introduced by Senator Allamand.
In May 2011, President Piñera said he was in favor of an upcoming bill to legalize a form of civil union; his stated intent was to "protect and safeguard [...] the dignity of those couples, whether of the opposite or even the same sex". Piñera introduced a bill to Congress in August 2011 allowing registered cohabitation, known as Acuerdo de Vida en Pareja ("Life Partnership Agreement"). This would give unmarried partners many of the rights granted only to married couples, such as inheritance and certain social welfare and health care benefits. Under Piñera's legislation, same-sex couples would be able to register their civil partnership with a notary. On 10 April 2013, the civil union bill was approved by the Senate's Constitution, Law and Justice Committee on a 4–1 vote. On 7 January 2014, the Senate voted 28–6 in favor, but the bill was not voted on by the Chamber of Deputies before the end of the parliamentary session in March 2014, despite it being a priority issue for Piñera.

### Bachelet's second presidency

When Michelle Bachelet again took office as president in March 2014, she made passing Piñera's civil union bill a priority. On 5 August 2014, a Senate committee approved the civil union bill. On 7 October 2014, the bill was passed by the Senate, and moved to the Chamber of Deputies.
The name of the bill was changed to "Civil Union Pact" (Spanish: Pacto de Unión Civil) on 17 December, and Congress reiterated its intention to hold a final vote by January 2015. On 6 January 2015, a provision recognizing foreign marriages as civil unions was approved by the Constitution Committee of the Chamber of Deputies, while a clause recognizing adoption rights was rejected. As the bill was amended, it went to a final vote in both the Senate and the Chamber of Deputies. On 13 January, the Chamber of Deputies reinserted the adoption provision, and on 20 January 2015 it approved the bill on a vote of 86 to 23 with 2 abstentions. The Senate rejected all the Chamber's amendments on 27 January, so the bill was sent to a joint committee of both houses. The committee reached an agreement with regard to the text of the bill and changed the name to "Civil Union Agreement" (Spanish: Acuerdo de Unión Civil, pronounced) the same day. The bill was passed in both houses on 28 January 2015. Several lawmakers asked the Constitutional Court to verify the bill's constitutionality, which was upheld by the court in a ruling released on 6 April 2015. The bill was signed into law by President Bachelet on 13 April 2015. It was published in the Diario Oficial de la República de Chile on 21 April and took effect on 22 October 2015.
Chile's civil union provisions enable couples to claim pension benefits and inherit property if their civil partner dies, as well as more easily co-own property and make medical decisions for one another. It does not allow couples to adopt. All disputes and conflicts involving civil partners are dealt with by the family courts (tribunales de familia). The government estimated at the time of the law going into effect that some two million cohabiting couples could have their unions legally recognized. In the day following the law going into effect, approximately 1,600 couples had signed up to register their unions. The first same-sex civil union on Easter Island was performed for Petero Avaka Tukuone and Aru Pate Hotus, a Mapuche-Rapa Nui couple, in November 2015.
On 1 December 2016, the Chamber of Deputies unanimously passed a bill (with six abstentions) granting civil partners five days' marriage leave, similarly to newly married couples. The bill was approved by the Senate in October 2017 in a unanimous 15–0 vote. The law took effect on 8 November 2017.

### Statistics

31,098 couples entered into civil unions between 2015 and 2019, of which 21% were same-sex couples (3,310 female couples and 3,271 male couples). This proportion was higher between October and December 2015 when 28.7% of civil unions were to same-sex couples. However, in the following months, this number declined and stabilized to around 20%.
Between 2016 and 2019, 248,567 marriages and 22,951 civil unions were performed in Chile, of which 5,950 were to same-sex couples. Most civil unions were performed in the Santiago Metropolitan Region (44%) followed by the Valparaíso Region (14%). Considering population, the region with the largest number of civil unions was Antofagasta (7.6 per 10,000 inhabitants), while the lowest was Araucanía (2.0 per 10,000 inhabitants). The Metropolitan Region also had the largest share of same-sex civil unions compared to opposite-sex unions (27%), followed by O'Higgins (22%) and Valparaíso (20%). On the other hand, Aysén had the lowest share of same-sex unions (8%), followed by Los Ríos (11%), Coquimbo (12%) and Magallanes (12%).

## Same-sex marriage
### Court cases

The first attempts to legalize same-sex marriage in Chile occurred after the ban was legally challenged in different national and international courts in the early 2010s. The Constitutional Court of Chile heard oral arguments on 28 July 2011 regarding the constitutionality of article 102 of the Civil Code, which at the time banned same-sex marriage, but ruled in a 9–1 vote on 3 November that the ban was not unconstitutional. A lawsuit challenging the same-sex marriage ban as a violation of the American Convention on Human Rights and Chile's international obligations was also filed with the Inter-American Court of Human Rights in 2012. The Piñera Government expressed its opposition to the suit in 2013.
On 10 June 2016, the Third Chamber of the Court of Appeals of Santiago rejected another lawsuit filed by the LGBT group MOVILH. The court ruled that as Chilean legislation did not permit same-sex marriages, the civil registry could not marry same-sex couples. It also held that opening marriage to same-sex couples was a decision for Congress and not for the courts.
In December 2018, the Supreme Court of Chile recognized marriage as a fundamental right, in a case legal experts suggested may pave the way for same-sex marriage to be legalized in Chile. Shortly after the ruling was issued, a same-sex couple challenged the same-sex marriage ban in court. On 26 April 2019, after the Supreme Court referred the case back to the Santiago Court of Appeals due to a probable constitutional violation, the latter ruled that denying the couple a marriage license was not illegal. The plaintiffs appealed the ruling to the Supreme Court; however, the appeal was not accepted.

### Agreement with the Inter-American Commission of Human Rights

Even though some minor presidential candidates had announced their support for same-sex marriage, Michelle Bachelet was the first major candidate to declare her support in the lead up to the November 2013 presidential elections. On 11 April 2013, she announced her intention to legalize same-sex marriage if elected president. Bachelet, who had previously been president of Chile between 2006 and 2010, won the election on 15 December 2013. After Bachelet's inauguration in March 2014, MOVILH announced that they would seek an amicable solution to the lawsuit presented to the Inter-American Court of Human Rights in 2012. On 10 December 2014, a group of senators from various parties presented a bill legalizing same-sex marriage and adoption to the National Congress of Chile, with the support of MOVILH. On 17 February 2015, lawyers representing the government and MOVILH met to discuss the case, and the government announced that they would drop their opposition to same-sex marriage. A formal agreement between the two parties and the Inter-American Commission of Human Rights was signed in April 2015.
On 1 July 2016, the government announced that it would begin consultations on a same-sex marriage bill in September 2016, with the aim of finalizing it by mid-2017, and said it viewed a ban on same-sex marriage as a "human rights violation". President Bachelet stated before a United Nations General Assembly panel in September 2016 that the Chilean Government would submit a same-sex marriage bill to Congress "in the first half of 2017." In June 2017, she announced in a speech to Congress that the bill would be introduced in the second half of 2017. It was later confirmed that the bill would grant married same-sex couples equal adoption rights. The bill was introduced to Congress on 28 August 2017, before being submitted to the Senate on 5 September and referred to the Constitution, Legislation, Justice and Regulation Committee.
On 19 November 2017, Chile held parliamentary elections and the first round of the presidential election. According to newspaper La Tercera, a majority of the newly elected Chamber of Deputies and Senate was in favor of same-sex marriage. The Senate's Constitution, Legislation, Justice, and Regulation Committee began examining the bill on 27 November 2017. Two days prior, an estimated 100,000 people marched in Santiago in favor of the bill's passage. Participants included many lawmakers and diplomats, including presidential candidate Alejandro Guillier.
On 17 December 2017, Sebastián Piñera was re-elected president of Chile. Though personally opposed to same-sex marriage at the time, Piñera said he would respect the April 2015 agreement with the Inter-American Commission of Human Rights, saying that "Chile's international commitments will be fulfilled". In the wake of a January 2018 Inter-American Court of Human Rights advisory opinion that parties to the American Convention on Human Rights should grant same-sex couples "accession to all existing domestic legal systems of family registration, including marriage, along with all rights that derive from marriage", MOVILH urged Piñera to implement and abide by the decision. In early March 2018, a spokesperson for the Piñera Administration announced that passing the same-sex marriage bill would not be a priority, but that the Piñera Government would not veto or oppose it. In early April 2018, the Inter-American Commission of Human Rights summoned the Chilean Government to a meeting to discuss the status of the measures included in the agreement reached in April 2015. The meeting took place in the Dominican Republic on 3 May 2018. The government informed the Commission that it would continue to respect the agreement. On 17 May 2018, the International Day Against Homophobia, Transphobia and Biphobia, Piñera signed the agreement and pledged to continue the work of the previous administration in legalizing same-sex marriage.

### Parliamentary debate and approval

Committee debate on the same-sex marriage bill resumed on 9 January 2019, and continued in May. In May 2019, Senate President Jaime Quintana said that the bill, along with a bill permitting same-sex couples to adopt, would have priority in the Senate agenda. In July 2019, upon assuming his role as chairman of the Constitution Committee, Senator Felipe Harboe began fast-tracking the procedure of the same-sex marriage bill, as opposition parties announced their intention to push for debate in Congress before going into recess in February 2020. On 15 January 2020, the bill was approved at first reading in the Senate by 22 votes to 16. In October 2020, it was reported that the Constitution Committee had approved 29 of the articles in the bill, with 27 remaining to be approved.
On 1 June 2021, during his last annual address to the National Congress, Piñera announced that his government would support the bill and place urgency on bringing it forward to a vote. On 21 July 2021, the Senate approved the legislation by 28 votes to 14. The bill then moved to the Chamber of Deputies. On 13 October 2021, the bill was approved by the Constitution Committee of the Chamber of Deputies, and on 2 November 2021 it was approved by the Finance Committee of the Chamber. On 23 November 2021, the Chamber of Deputies approved an amended version by 101 votes to 30. As it was modified by the Chamber of Deputies, the Senate Constitution Committee decided to send the bill to a joint committee of both houses. On 6 December, the joint committee voted 7–2 in favor of the Chamber version of the bill with modifications, including a compromise provision that spouses of transgender people wishing to change their name and legal gender should first be consulted as to whether they wish to seek a divorce, which was criticized by MOVILH as "transphobic".

Article 102 of the Civil Code was amended to read: Marriage is a solemn, indissoluble contract by which two persons are united for life, in order to live together, to procreate, and to help each other.

### Attempts to modify constitution

In response to proposed legislation to recognize same-sex unions and potential legal battles brewing in the Constitutional Court, members of the Independent Democrat Union (UDI) introduced a constitutional amendment on 11 August 2011 seeking to define marriage as the "union of a man and a woman". The amendment was not brought to a vote. On 16 June 2016, two UDI MPs introduced a bill to amend the Constitution of Chile to ban same-sex marriage and prohibit same-sex couples from adopting. The measure was not successful.
In October 2020, Chile voted in a national plebiscite to rewrite its constitution, and in a May 2021 election voters elected the members of the Constitutional Convention, the body tasked with writing the new constitution. LGBT groups were hopeful that same-sex marriage and adoption rights for same-sex couples would be enshrined in this new constitution, particularly as the right-wing governing coalition Chile Vamos had failed to reach the third of members needed to veto in the Convention. The proposed constitution, which eventually did not address same-sex marriage explicitly, was rejected in a referendum in September 2022.

### Statistics

In the first month following the entry into force of the marriage law, 170 same-sex couples had married in Chile, of which 101 were lesbian couples. By February 10, 2023, 2,254 same-sex marriages had been performed in Chile; 1,227 between two women and 1,027 between two men. 5,049 same-sex marriages had taken place by June 2024, mostly in the Santiago Metropolitan Region. Reports in December 2024 determined that 6,281 same-sex couples had married in Chile since the implementation of the law.

### Religious performance

In 2011, the Evangelical Lutheran Church in Chile expressed its support for same-sex civil unions. The church defines marriage as "a union of two people in love based on mutual trust and fidelity" without making distinction as to the sex of the contracting parties. Clergy are free to decide whether to perform blessings for same-sex couples. The Lutheran Church in Chile similarly defines marriages as "a union of two people in love" and offers blessings to couples. Some Jewish groups also bless same-sex unions. On 25 February 2023, a same-sex marriage was held according to the rites of the Mapuche religion. The couple, Viviana Burgos Valenzuela and Rosa Salamanca Conalef, had held a civil marriage two days earlier in the town of Villa Almagro in Nueva Imperial. The religious ceremony was officiated by a Mapuche spiritual leader (machi) in a native forest.
The Catholic Church opposes same-sex marriage and does not allow its priests to officiate at such marriages. In December 2023, the Holy See published Fiducia supplicans, a declaration allowing Catholic priests to bless couples who are not considered to be married according to church teaching, including the blessing of same-sex couples. In March 2004, Archbishop of Santiago Francisco Javier Errázuriz Ossa expressed opposition to same-sex marriage but called for regulating same-sex unions "in some way"; "One can understand that homosexuals can form stable relationships, that they want to have a community property, but that is not marriage. It must be given another name."
