Lesbian, gay, bisexual, transgender, and queer (LGBTQ) persons in the U.S. state of Missouri as of late have most of the same legal rights as non-LGBT persons have, but nonetheless face some legal challenges not experienced by other residents throughout the state, excluding St. Louis, Kansas City, and Columbia. Same-sex sexual activity is legal in Missouri.
Missouri recognizes same-sex marriages. A state court ruling striking down Missouri's same-sex marriage ban ordered the City of St. Louis to issue marriage licenses to same-sex couples. St. Louis County and Jackson County also issue marriage licenses to same-sex couples. On June 26, 2015, the decision of the U.S. Supreme Court in Obergefell v. Hodges invalidated the denial of marriage rights to same-sex couples, including Missouri's.
