12 nations bound by Inter-American Court ruling
"THE COURT DECIDES ... by six votes to one that: ... Under Articles 1(1), 2, 11(2), 17 and 24 of the [American] Convention [on Human Rights], States must ensure full access to all the mechanisms that exist in their domestic laws, including the right to marriage, to ensure the protection of the rights of families formed by same-sex couples, without discrimination in relation to those that are formed by heterosexual couples, as established in paragraphs 200 to 228."
In a binding ruling made on Nov. 24, 2017, and published Jan. 9, 2018, the Inter-American Court of Human Rights instructed 20 nations that are signatories to the American Convention on Human Rights to let same-sex couples marry: Argentina, Barbados, Bolivia, Brazil, Chile, Colombia, Costa Rica, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Suriname and Uruguay. Eight of the nations — Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, Mexico and Uruguay — have marriage equality. Courts in Ecuador and Costa Rica brought in marriage equality because of the Inter-American Court ruling.
"All countries are obligated to apply the Convention as the court applies it, so it is binding on all as precedent," said Hunter T. Carter, a partner at Arent Fox who has tried a case in the Inter-American Court and represented Chilean same-sex couples in the Inter-American system.
Overseas municipalities Bonaire, Saba and Sint Eustatius have marriage equality. Constituent countries Aruba, Curaçao and Sint Maarten do not, though they partially recognize Dutch marriages from elsewhere.
Mexico achieved marriage equality state-by-state between March 2010 and October 2022. My article on how it played out is here.
All overseas departments and collectivities — see the France entry above — have marriage equality. The links above show a same-sex couple marrying in nine of the 11 jurisdictions.
Nineteen UK-associated jurisdictions have marriage equality: England and Wales (2014), Akrotiri and Dhekelia (2014), British Indian Ocean Territory (2014, 2015), Scotland (2014), South Georgia and the South Sandwich Islands (2014), Pitcairn Islands (2015), Ascension Island (2016), Isle of Man (2016), British Antarctic Territory (2016), Gibraltar (2016), Guernsey (2017), Falkland Islands (2017), Tristan da Cunha (2017), Saint Helena (2017), Jersey (2018), Alderney (2018), Northern Ireland (2020), and Sark (2020).
Six British overseas territories do not have marriage equality: Anguilla, Bermuda, British Virgin Islands, Cayman Islands, Montserrat, and Turks and Caicos Islands.
Bermuda had marriage equality in 2017 and again from 2018 to 2022. It was terminated on March 14, 2022, by the court of final appeal, the Judicial Committee of the Privy Council in the United Kingdom. The judgment is here. The Cayman Islands had marriage equality for 13 days in 2019. It was blocked with finality on March 14, 2022, by the court of final appeal, the Judicial Committee of the Privy Council in the United Kingdom. The judgment is here.
The six remaining UK jurisdictions can still achieve marriage equality if their legislatures pass it, if the UK government imposes it, or possibly via the European Court of Human Rights. There is also a case from the British Virgin Islands before the Eastern Caribbean Supreme Court.
On May 22, 2015, Ireland became the first nation to bring in marriage equality by popular vote. Irish people amended their constitution by a landslide margin of 62.07% to 37.93%.
Four of the five U.S. territories — Guam, Northern Mariana Islands, Puerto Rico, U.S. Virgin Islands — were covered by the U.S. Supreme Court's nationwide marriage-equality ruling on June 26, 2015. American Samoa was not.
The United States Minor Outlying Islands — Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Palmyra Atoll and Wake Island in the Pacific Ocean, and Navassa Island in the Caribbean Sea — would have marriage equality. Their population nowadays is a small number of temporarily assigned scientists and military personnel.
Same-sex couples can marry in Antarctica. Nations that claim portions of the continent include Argentina, Australia, Chile, France, New Zealand, Norway and the United Kingdom, all of which have marriage equality.
On the high seas

U.S. Indian tribes
There are 574 of them and they are not covered by the June 26, 2015, U.S. Supreme Court ruling that brought in marriage equality nationwide. At least 32 tribes, listed below, have legalized same-sex marriage to date. A number of others follow the marriage law of the state in which they are located, so marriage equality is in place without additional tribal action.
