Lesbian, gay, bisexual, and transgender (LGBT) persons in the U.S. state of Arkansas face legal challenges not experienced by non-LGBT residents. Same-sex sexual activity is legal in Arkansas. Same-sex marriage became briefly legal through a court ruling on May 9, 2014,^[1] subject to court stays and appeals. In June 2015, the U.S. Supreme Court ruled in Obergefell v. Hodges that laws banning same-sex marriage are unconstitutional, legalizing same-sex marriage in the United States nationwide including in Arkansas. Nonetheless, discrimination on the basis of sexual orientation and gender identity was not banned in Arkansas until the Supreme Court banned it nationwide in Bostock v. Clayton County in 2020.

In 1838, Arkansas instituted the first statute against homosexual activity with a provision which read: "Every person convicted of sodomy or buggery will be imprisoned in the state penitentiary for not less than five years nor more than 21 years." In 1864, the Arkansas General Assembly raised the penalty to death, though this was repealed 9 years later, and the initial penalty was re-established. The first reported sodomy case occurred in 1921 in Smith v. State, where the defendant was found guilty of "disregarding the laws of nature". In 1925, the Arkansas Supreme Court unanimously held that fellatio (oral sex), whether heterosexual or homosexual, violated the sodomy statute. The legislation was subsequently amended in 1955 to lower the minimum penalty to one-year imprisonment, and in 1977 to penalize only homosexual acts, or sexual acts occurring between humans and animals; but in effect decriminalized sodomy by making it a Class A misdemeanor.^[2]

In 1992, Governor Bill Clinton, during his presidential campaign, publicly called for the sodomy law to be repealed. The statement was published on the front page of the Washington Blade's 22 May 1992 issue.^[2]

In 2002, the Arkansas Supreme Court in Picado v. Jegley found that the state statute that made sexual relations between people of the same gender a criminal act was unconstitutional because the law violated a fundamental right to privacy and failed to provide the equal protection of the laws.^[3][4] Previously, the courts had rejected multiple legal challenges to the statute: Connor v. State (1973) where the state Supreme Court rejected arguments that religious prejudice in the law's enactment made it unconstitutional, Carter et al. v. State (1973) where the same court held that the General Assembly could, "within constitutional limits", outlaw anything that was "hurtful to the comfort, safety and welfare of the people and prescribe regulations to promote the public health, morals and safety" and rejected privacy as a fundamental right, and United States v. Lemmons (1983) in which a federal court rejected privacy arguments based on the fact that the act in question had occurred in a public restroom.^[2]

On April 4, 2005, the Arkansas House of Representatives passed, by a vote of 85–0 in favor, SB 984, a bill repealing laws against sexual acts among same-sex couples. On April 7, 2005, the Arkansas State Senate passed the bill, by a vote of 35–0 in favor. Governor Mike Huckabee signed the bill into law, and it went into effect on April 12, 2005.^[5]

Arkansas bans same-sex marriage in both state statute and its state Constitution. These provisions have been ruled unconstitutional and are no longer enforced.^[1]

On May 9, 2014, Sixth Judicial Circuit Judge Chris Piazza issued a preliminary ruling in Wright v. Arkansas that found the state's ban on same-sex marriage unconstitutional. On May 15, he issued a final ruling that enjoined enforcement of the state's statutes prohibiting the licensing and recognition of same-sex marriages as well. The Arkansas Supreme Court stayed his ruling while it heard the appeal in the case.^[6]

In another lawsuit in federal court, Jernigan v. Crane, on November 25, 2014, Judge Kristine Baker found the state's ban on same-sex marriage unconstitutional and stayed her ruling pending appeal.^[7]

On June 26, 2015, the U.S. Supreme Court ruled in Obergefell v. Hodges that bans on same-sex marriage are unconstitutional, effectively legalizing same-sex marriage in the United States. Since then, same-sex couples in Arkansas have been allowed to legally wed.^[8]

Arkansas voters approved a ballot measure in November 2008, effective from January 1, 2009, to prohibit by statute cohabiting couples who are not in a recognized marriage from adopting and providing foster care.^[9] On April 7, 2011, in Arkansas Department of Human Services v. Cole, the Arkansas Supreme Court unanimously found that the measure "fails to pass constitutional muster" because it "directly and substantially burdens the privacy rights of 'opposite-sex and same-sex individuals' who engage in private, consensual sexual conduct in the bedroom by foreclosing their eligibility to foster or adopt children, should they choose to cohabit with their sexual partner."^[10]

Lesbian couples have access to in vitro fertilization and other assisted reproduction services. Per Pavan v. Smith, Arkansas recognizes the non-genetic, non-gestational mother as a legal parent to a child born via donor insemination, but only if the parents are married.^[11] In addition, no statute or case law prohibits surrogacy, traditional or gestational. As a result, both are practiced in the state, including by same-sex couples.^[12]

Arkansas law does not address discrimination based on gender identity or sexual orientation.^[17]

The capital city of Little Rock and several other cities, including Conway, Hot Springs and North Little Rock as well as Pulaski County, prohibit discrimination on the basis of sexual orientation and gender identity in public employment (city or county employees).^[18] The cities of Marvell and Springdale have similar policies but only ban sexual orientation-based discrimination.^[19]

Two cities have enacted comprehensive anti-discrimination ordinances addressing both public and private employment discrimination on account of sexual orientation and gender identity. These are Eureka Springs and Fayetteville.^[20] However, both these ordinances are unenforced due to the passage of the Intrastate Commerce Improvement Act. In February 2017, the Arkansas Supreme Court struck down Fayetteville's anti-discrimination ordinance because it included sexual orientation and gender identity as protected categories. The court found that the ordinance contravened the act.^[21] Following the ruling, Fayetteville City Attorney Kit Williams said he would focus on challenging the constitutionality of the act.

Arkansas has no hate crime statute that attaches penalties to criminal convictions when motivated by bias,^[23] but a state statute does allow victims to sue for damages or seek court-ordered relief for acts of intimidation, harassment, violence, or property damage "where such acts are motivated by racial, religious, or ethnic animosity", not sexual orientation or gender identity.^[24] However, sexual orientation and gender identity are covered under U.S. federal law since the Matthew Shepard and James Byrd, Jr. Hate Crimes Prevention Act was signed into law in October 2009.

In early 2021, a bill (SB 289) to allow medical practitioners to cite their religious beliefs to deny healthcare to LGBT patients passed the Arkansas House of Representatives and the Arkansas Senate.^[29][30][31] Both Mississippi and Illinois have similar laws.^[32] On March 26, Governor Asa Hutchinson signed the bill into law effective immediately.^[33]

Since 1981, Arkansas law permits transgender people to amend their birth certificates upon receipt of a court order verifying that they have undergone sex reassignment surgery and that their names have been changed.^{[34][35][36][37]}

Besides male and female, Arkansas identity documents are available with an "X" sex descriptor. The Arkansas Department of Finance and Administration has issued such documentation since December 2010.^[38] In March 2024, the DFA rescinded its support of X descriptors for driver's licences. ^[39]

A 2017 Public Religion Research Institute (PRRI) poll found that 52% of Arkansas residents supported same-sex marriage, while 38% opposed it and 10% were unsure.^[60] The same poll found that 64% of Arkansans supported an anti-discrimination law covering sexual orientation and gender identity, while 27% were opposed.^[61] Furthermore, 53% were against allowing public businesses to refuse to serve LGBT people due to religious beliefs, while 41% supported allowing such religiously-based refusals.^[62]

A 2022 Public Religion Research Institute(PRRI) poll found that 51% of Arkansas residents supported same-sex marriage, while 47% opposed it and 1% were unsure. The same poll found that 74% of Arkansans supported an anti-discrimination law covering sexual orientation and gender identity, while 24% were opposed. 2% were undecided. Furthermore, 55% were against allowing public businesses to refuse to serve LGBT people due to religious beliefs, while 43% supported allowing such religiously-based refusals. 1% were undecided.
