States with the freedom to marry do not ban same-sex couples from entering into legal marriages. Some states also offer comprehensive relationship recognition, such as domestic partnerships or civil unions, to same- and different-sex couples. However, most states still have constitutional amendments, statutes, or both banning marriage for same-sex couples, even after the 2015 Supreme Court case Obergefell extended marriage equality nationwide. For more on the current status of state marriage laws, see MAP's 2022 report: Underneath Obergefell: A National Patchwork of Marriage Laws.

NOTE: Kansas permits faith-based organizations to deny services to married same-sex couples. North Carolina permits state officials to decline to marry couples of whose marriage they disapprove. Mississippi passed a law in 2016 permitting state officials to decline to marry couples of whose marriage they disapprove; H.B. 1523 (2016); this law has been challenged and overturned by a federal court and is currently stayed from enforcement. For additional information, contact Freedom to Marry, Lambda Legal, Gay & Lesbian Advocates & Defenders or ACLU LGBT Rights Project.
The 2015 U.S. Supreme Court ruling in Obergefell extended marriage to same-sex couples nationwide. In the U.S. territories, however, there is some question as to the “on the ground” implementation of the Court’s 2015 ruling. For more information, please see MAP's U.S. territory policy spotlight.
Additionally, several Native American jurisdictions extend marriage rights to same-sex couples. These jurisdictions are federally recognized sovereign nations and therefore can create their own policies around same-sex partnerships. The following is a list of Native American nations that have legalized same-sex marriage followed by the year in which the ruling was made. Several nations passed laws to offer the freedom to marry, whereas others have issued marriage licenses to same-sex couples based on a reinterpretation of tribal codes.

Despite the 2015 Supreme Court case Obergefell, which extended marriage equality nationwide, many states still have constitutional amendments, statutes (i.e., legislation), or both banning marriage for same-sex couples. The 2015 ruling means these bans are unenforceable. For more, see also MAP's 2022 report: Underneath Obergefell: A National Patchwork of Marriage Laws. The below map is updated and maintained in real time.
Note: Currently all of these bans are unenforceable due to a 2015 U.S. Supreme Court ruling in Obergefell.
-
State has both statutory and constitutional amendment ban
(24 states)
-
State has constitutional amendment ban only
(3 states)
-
State has statutory (i.e., legislative) ban only
(6 states)
-
State has no ban on marriage equality
(17 states , 5 territories + D.C.)
-

*Note: In November 2024, voters in California, Colorado, and Hawaii repealed their constitutional amendments regarding marriage. In Colorado, the state still has a statutory ban on the books, though this remains unenforceable due to Obergefell. Recommended citation:
