Lesbian, gay, bisexual, and transgender (LGBT) persons in the U.S. state of Louisiana face some legal challenges not experienced by non- LGBT residents. Same-sex sexual activity is legal in Louisiana and same-sex marriage has been legal in the state since June 2015. Nevertheless, discrimination based on sexual orientation and gender identity is not banned statewide.
In September 2014, two courts, one federal and one state, produced contradictory rulings on the constitutionality of the state's denial of marriage rights to same-sex couples. The U.S. Supreme Court resolved that conflict when it ruled such bans unconstitutional in Obergefell v. Hodges on June 26, 2015. Two days later, Governor Bobby Jindal said the state would comply with that ruling and license same-sex marriages.
There were no laws against same-sex sexual acts in Louisiana until 1805, when Louisiana enacted its first Penal Code after annexation by the United States. 
Sexual acts between persons of the same sex are legal in Louisiana. They were previously criminalized under the state's sodomy law, which applied to both homosexuals and heterosexuals. The law was rendered unenforceable in 2003 by the U.S. Supreme Court's decision in Lawrence v. Texas. 
In 2005, the United States Court of Appeals for the Fifth Circuit struck down the part of the statute that criminalized adult consensual anal and oral sex. 
In 2013, law enforcement officers in East Baton Rouge Parish arrested men who had engaged in sexual activity banned by the statute. The District Attorney did not prosecute those arrested, and both he and the parish sheriff supported repealing the sodomy statute. In April 2014, a bill to repeal the statute failed in the Louisiana House of Representatives on a 66–27 vote after lobbying in opposition by the Louisiana Family Forum, thus keeping an unconstitutional law on the books.  
In early May 2018, the Louisiana House of Representatives unanimously approved a bill toughening laws against bestiality and separating them from the unconstitutional sodomy law. The Senate passed the bill later that month in a 36-1 vote, and it was signed into law by Governor John Bel Edwards on May 25. Initially, ten Republican lawmakers stated their opposition to the anti-bestiality bill, which was also opposed by conservative groups, including the Louisiana Family Forum.  
The U.S. Supreme Court's ruling in Obergefell v. Hodges on June 26, 2015, held that the denial of marriage rights to same-sex couples is unconstitutional, invalidating the ban on same-sex marriage in Louisiana.
In 1988 and 1999, Louisiana added provisions to its Civil Code that prohibited same-sex couples from marrying and prohibited the recognition of same-sex marriages from other jurisdictions.   Louisiana added bans on same-sex marriage and civil unions in its Constitution in 2004. 
Two lawsuits challenged the state's bans. In state court in Costanza v. Caldwell, the plaintiffs won initially, but the ruling was stayed pending appeal, which was left unresolved after oral argument was heard on January 29, 2015.   In federal court in Robicheaux v. George, plaintiffs challenged the state's refusal to recognize same-sex marriages from other jurisdictions. U.S. District Judge Martin Feldman ruled on September 3, 2014, for the state, writing that "Louisiana has a legitimate interest ... whether obsolete in the opinion of some, or not, in the opinion of others ... in linking children to an intact family formed by their two biological parents".  On appeal to the Fifth Circuit Court of Appeals, the case remained unresolved at the time of the U.S. Supreme Court decision in Obergefell on June 26, 2015. Following the Supreme Courts ruling, the Fifth Circuit Court of Appeals remanded the case back to the District Court, where Judge Feldman reversed his order ruling in favor of the Robicheaux plaintiffs.
On September 22, 2014, state trial court Judge Edward Rubin found Louisiana's prohibition of allowing married same-sex couples to adopt to be unconstitutional and granted the first same-sex adoption in the state of Louisiana in Costanza v. Caldwell. 
Louisiana has successfully defended in federal court its refusal to amend the birth certificate of a child born in Louisiana and adopted in New York by a married same-sex couple, who sought to have a new certificate issued with their names as parents as is standard practice for Louisiana-born children adopted by opposite-sex married couples.  On October 11, 2011, the U.S. Supreme Court rejected a request from Lambda Legal, representing the plaintiffs in the case, Adar v. Smith, to review the case. 
On February 17, 1992, Governor Edwin Edwards issued an executive order prohibiting discrimination in state employment on the basis of sexual orientation.  In August 1996, Governor Murphy J. Foster, Jr. allowed the executive order to lapse. On December 4, 2004, Governor Kathleen Blanco reissued Edwards' executive order.  In August 2008, Governor Bobby Jindal allowed it to expire.   On April 13, 2016, Governor John Bel Edwards reinstated the provision,  as announced shortly after his election.  However, Bel Edwards's order was struck down in November 2017 by an appellate court who found that the Governor had overstepped his authority.  In March 2018, the Louisiana Supreme Court upheld the appellate court ruling. 
In May 2015, a House committee rejected a bill that would have protected people who exercise their religious beliefs on same-sex marriage. However, Governor Jindal then issued an executive order to that end.  On April 13, 2016, Governor Edwards rescinded that executive order.
On April 28, 2016, the Senate Labor Committee approved in a 4–3 vote a bill that would have banned employment discrimination based on sexual orientation or gender identity.  The bill, however, didn't advance any further and died at the end of the legislative term.
The cities of New Orleans,  and Shreveport   prohibit discrimination on the basis of sexual orientation and gender identity. Alexandria, Baton Rouge, Lafayette, and Lake Charles along with the parish of Jefferson prohibit discrimination against public employees only.
Louisiana is one of the few southern states which has a hate crime law that provides for penalty enhancements for crimes motivated by the victim's sexual orientation or perceived sexual orientation.  Passed in 1997, after a lobbying effort of five years, its passage made Louisiana the first state in the Deep South to have such a law.  It does not cover gender identity.
In June 2017, the Louisiana Legislature (House vote 54-42 and Senate vote 25-13) passed a bill called HB27, to repeal the words "opposite-sex" from the domestic violence statutes. The bill was signed into law by the Governor of Louisiana, John Bel Edwards, and went into full effect on August 1, 2017.  At that time, South Carolina was the only state left in the United States to still explicitly only include "people of the opposite-sex" within its domestic violence laws. 
Following the U.S. Supreme Court decision in United States v. Windsor in June 2013 invalidating Section 3 of the Defense of Marriage Act, the U.S. Department of Defense issued directives requiring state units of the National Guard to enroll the same-sex spouses of guard members in federal benefit programs. Defense Secretary Chuck Hagel on October 31 said he would insist on compliance.  On December 3, Louisiana agreed to conform with DoD policy stating that state workers would be considered federal workers while enrolling same-sex couples for benefits. 
Recent polls have found that, while Louisianians are mostly evenly split in support and opposition to same-sex marriage, support is increasing and opposition is decreasing.
A 2017 Public Religion Research Institute (PRRI) poll found that 48% of Louisianans supported same-sex marriage, while 44% were opposed. 8% were undecided. Additionally, 61% supported an anti-discrimination law covering sexual orientation and gender identity. 29% were against. The PRRI also found that 54% were against allowing public businesses to refuse to serve LGBT people due to religious beliefs, while 37% supported such religiously-based refusals.
