Sodomy laws in the United States, which outlawed a variety of sexual acts, were inherited from British criminal laws with roots in the Christian religion of Late antiquity.  While they often targeted sexual acts between persons of the same sex, many statutes employed definitions broad enough to outlaw certain sexual acts between persons of different sexes as well, sometimes also acts between married persons.
Through the 20th century, the gradual liberalization of American sexuality led to the elimination of sodomy laws in most states. During this time, the Supreme Court upheld the constitutionality of sodomy laws in Bowers v. Hardwick in 1986. However, in 2003 the Supreme Court reversed the decision with Lawrence v. Texas, invalidating sodomy laws in the remaining 14 states ( Alabama, Florida, Idaho, Kansas, Louisiana, Michigan, Mississippi, Missouri (statewide), North Carolina, Oklahoma, South Carolina, Texas, Utah, and Virginia).
Colin Talley argues that the sodomy statutes in colonial America in the 17th century were largely unenforced. The reason he argues is that male-male eroticism did not threaten the social structure, or challenge the gendered division of labor or the patriarchal ownership of wealth. . There were gay men on General Washington's staff and among the leaders of the new republic.  In 1779, Thomas Jefferson wrote a law in Virginia which contained a punishment of castration for men who engage in sodomy.  Jefferson intended this to be a liberalization of the sodomy laws in Virginia at that time, which prescribed death as the maximum penalty for the crime of sodomy. It was rejected by the Virginia legislature. 
Prior to 1962, sodomy was a felony in every state, punished by a lengthy term of imprisonment and/or hard labor. In that year, the Model Penal Code (MPC) — developed by the American Law Institute to promote uniformity among the states as they modernized their statutes — struck a compromise that removed consensual sodomy from its criminal code while making it a crime to solicit for sodomy. In 1962 Illinois adopted the recommendations of the Model Penal Code and thus became the first state to remove criminal penalties for consensual sodomy from its criminal code,  almost a decade before any other state. Over the years, many of the states that did not repeal their sodomy laws had enacted legislation reducing the penalty. At the time of the Lawrence decision in 2003, the penalty for violating a sodomy law varied very widely from jurisdiction to jurisdiction among those states retaining their sodomy laws. The harshest penalties were in Idaho, where a person convicted of sodomy could earn a life sentence. Michigan followed, with a maximum penalty of 15 years imprisonment while repeat offenders got life.[ citation needed]
By 2002, 36 states had repealed their sodomy laws or their courts had overturned them. By the time of the 2003 Supreme Court decision, the laws in most states were no longer enforced or were enforced very selectively. The continued existence of these rarely enforced laws on the statute books, however, was often cited as justification for discrimination against gay men, lesbians, and bisexuals.
On June 26, 2003, the U.S. Supreme Court in a 6–3 decision in Lawrence v. Texas struck down the Texas same-sex sodomy law, ruling that this private sexual conduct is protected by the liberty rights implicit in the due process clause of the United States Constitution. This decision invalidated all state sodomy laws insofar as they applied to noncommercial conduct in private between consenting civilians and reversed the Court's 1986 ruling in Bowers v. Hardwick that upheld Georgia's sodomy law.
Before that 2003 ruling, 27 states, the District of Columbia, and 4 territories had repealed their sodomy laws by legislative action, 9 states had had them overturned or invalidated by state court action, 4 states still had same-sex sodomy laws, and 10 states, Puerto Rico, and the U.S. military had laws applying to all regardless of gender. In 2005 Puerto Rico repealed its sodomy law, and in 2006 Missouri repealed its law against "homosexual conduct". In 2013, Montana removed "sexual contact or sexual intercourse between two persons of the same sex" from its definition of deviate sexual conduct, Virginia repealed its lewd and lascivious cohabitation statute, and sodomy was legalized in the US armed forces.
Louisiana's statutes still include "unnatural carnal copulation by a human being with another of the same sex" in their definition of " crimes against nature", punishable (in theory) by a fine of up to $2,000 or a prison sentence of up to five years, with or without hard labor;  however, this section was further mooted by the United States Court of Appeals for the Fifth Circuit in 2005 in light of the Lawrence decision. 
In State v. Whiteley (2005), the North Carolina Court of Appeals ruled that the crime against nature statute, N.C. G.S. § 14-177,  is not unconstitutional on its face because it may properly be used to criminalize sexual conduct involving minors, non-consensual or coercive conduct, public conduct, and prostitution. 
On January 31, 2013, the Senate of Virginia passed a bill repealing § 18.2-345, the lewd and lascivious cohabitation statute enacted in 1877, by a vote of 40 to 0. On February 20, 2013, the Virginia House of Delegates passed the bill by a vote of 62 to 25 votes. On March 20, 2013, Governor Bob McDonnell signed the repeal of the lewd and lascivious cohabitation statute from the Code of Virginia. 
On March 12, 2013, a three-judge panel of the Court of Appeals for the Fourth Circuit struck down § 18.2-361, the crimes against nature statute. On March 26, 2013, Attorney General of Virginia Ken Cuccinelli filed a petition to have the case reheard en banc, but the Court denied the request on April 10, 2013, with none of its 15 judges supporting the request.  On June 25, Cuccinelli filed a petition for certiorari asking the U.S. Supreme Court to review the Court of Appeals decision, which was rejected on October 7.  
On February 7, 2014, the Virginia Senate voted 40-0 in favor of revising the crimes against nature statue to remove the ban on same-sex sexual relationships. On March 6, 2014, the Virginia House of Delegates voted 100-0 in favor of the bill. On April 7, the Governor submitted slightly different version of the bill. It was enacted by the Legislature on April 23, 2014. The law took effect upon passage. 
In April 2014, a proposed Louisiana bill sought to revise the state's crime against nature law, maintaining the existing prohibition against sodomy during the commission of rape and child sex abuse, and against sex with animals, but removing the unconstitutional prohibition against sex between consenting adults. The bill was defeated on April 15, 2014 by a vote of 66 to 27. 
As of April 2014, 17 states either have not yet formally repealed their laws against sexual activity among consenting adults, or have not revised them to accurately reflect their true scope in the aftermath of Lawrence v. Texas. Often, the sodomy law was drafted to also encompass other forms of sexual conduct such as bestiality, and no attempt has subsequently succeeded in separating them. Fourteen states' statutes purport to ban all forms of sodomy, some including oral intercourse, regardless of the participants' genders: Alabama, Florida, Georgia, Idaho, Louisiana, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, North Carolina, Oklahoma, South Carolina, and Utah. Three states specifically target their statutes at same-sex relations only: Kansas,   Kentucky, and Texas.

Sodomy laws in the United States were largely a matter of state rather than federal jurisdiction, except for laws governing the District of Columbia and the U.S. Armed Forces.
In 1801, Congress enacted the District of Columbia Organic Act of 1801 that continued all criminal laws of Maryland and Virginia in the now formally structured District, with those of Maryland applying to that portion of the District ceded from Maryland, and those of Virginia applying to that portion ceded from Virginia. At the time, Maryland had a sodomy law applicable only to free males with a punishment of "labour for any time, in their discretion, not exceeding seven years for the same crime, on the public roads of the said county, or in making, repairing or cleaning the streets or bason [sic] of Baltimore-town" and the death penalty for slaves committing sodomy, while Virginia had a penalty of 1–10 years for free persons committing sodomy, but had the death penalty for slaves committing sodomy. The law went into effect on February 27, 1801. 
In 1831, Congress established penalties in the District of Columbia for a number of crimes, but not for sodomy. It specified that "every other felony, misdemeanor, or offence not provided for by this act, may and shall be punished as heretofore[.]" At the time, Maryland and Virginia had a penalty of 1–10 years for committing sodomy. It went into effect in March 2, 1831. 
In 1892, Congress passed a law for the District of Columbia that states that "for the preservation of the public peace and the protection of property within the District of Columbia." Labeled in the law as vagrants were "all public prostitutes, and all such persons who lead a notoriously lewd or lascivious course of life[.]" All offenders had to post bond of up to $200 for good behavior for a period of six months. The law went into effect on July 29, 1892. 
In 1898, Congress deleted the word "notoriously" from the provision concerning a lewd or lascivious course of life, thereby allowing prosecution of those without notoriety. The bond for good behavior was raised to $500, and the law was made clearly gender-neutral. The law went into effect on July 8, 1898. 
In 1901, Congress adopting a new code for the District of Columbia that expressly recognized common-law crimes, with a penalty for them of up to five years and/or a $1,000 fine. The law went into effect on March 3, 1901. 
In 1935, Congress passed a law for the District of Columbia that made it a crime for "any person to invite, entice, persuade, or to address for the purpose of inviting, enticing, or persuading any person or persons...to accompany, to go with, to follow him or her to his or her residence, or to any other house or building, inclosure, or other place, for the purpose of prostitution, or any other immoral or lewd purpose." It imposed a fine of up to $100, up to 90 days in jail, and courts were permitted to "impose conditions" on anyone convicted under this law, including "medical and mental examination, diagnosis and treatment by proper public health and welfare authorities, and such other terms and conditions as the court may deem best for the protection of the community and the punishment, control, and rehabilitation of the defendant." The law went into effect on August 14, 1935. 
In 1941, Congress enacted a new solicitation law for the District of Columbia that labeled a "vagrant" any person who "engages in or commits acts of fornication or perversion for hire." The law went into effect on December 17, 1941. 
In 1948, Congress enacted the first sodomy law in the District of Columbia, which established a penalty of up to 10 years in prison or a fine of up to $1,000 for sodomy. Also included with this sodomy law was a psychopathic offender law and a law "to provide for the treatment of sexual psychopaths in the District of Columbia, and for other purposes." The law went into effect on June 9, 1948. 
In 1953, Congress changed the solicitation law in the District of Columbia so that the jail term of up to 90 days was retained, but the maximum fine was raised to $250, and the reference to the power of judges to "impose conditions" on the defendant was removed. The law went into effect on June 29, 1953. 
In 1981, after the District of Columbia regained home rule from Congress, it enacted a law that repealed the sodomy law, as well as other consensual acts, and made the sexual assault laws gender-neutral. However, the U.S. House exercised the power that it retained to veto laws passed by the District of Columbia Council. On October 1, 1981, the House voted 281-119 to disallow the new law.       In 1983, one of the House vetoes by Congress was declared unconstitutional by the U.S. Supreme Court in the case of Immigration and Naturalization Service v. Chadha, but the law was repealed by an act of Congress in a revision to the home-rule law required by the Supreme Court decision. 
In 1993, the District of Columbia passed a law repealing the sodomy law, but this time Congress did not interfere and allowed the law to go into effect. 
Although the U.S. military discharged soldiers for homosexual acts throughout the eighteenth and nineteenth century, U.S. military law did not expressly prohibit homosexuality or homosexual conduct until February 4, 1921. 
On March 1, 1917, the Articles of War of 1916 were implemented. This included a revision of the Articles of War of 1806, the new regulations detail statutes governing U.S. military discipline and justice. Under the category Miscellaneous Crimes and Offences, Article 93 states that any person subject to military law who commits "assault with intent to commit sodomy" shall be punished as a court-martial may direct. 
On June 4, 1920, Congress modified Article 93 of the Articles of War of 1916. It was changed to make the act of sodomy itself a crime, separate from the offense of assault with intent to commit sodomy.  It went into effect on February 4, 1921. 
On May 5, 1950, the UCMJ was passed by Congress and was signed into law by President Harry S. Truman, and became effective on May 31, 1951. Article 125 forbids sodomy among all military personnel, defining it as "any person subject to this chapter who engages in unnatural carnal copulation with another person of the same or opposite sex or with an animal is guilty of sodomy. Penetration, however slight, is sufficient to complete the offence." 
As for the U.S. Armed Forces, the Court of Appeals for the Armed Forces has ruled that the Lawrence v. Texas decision applies to Article 125, severely narrowing the previous ban on sodomy. In both United States v. Stirewalt and United States v. Marcum, the court ruled that the "conduct [consensual sodomy] falls within the liberty interest identified by the Supreme Court,"  but went on to say that despite the application of Lawrence to the military, Article 125 can still be upheld in cases where there are "factors unique to the military environment" that would place the conduct "outside any protected liberty interest recognized in Lawrence."  Examples of such factors include rape, fraternization, public sexual behavior, or any other factors that would adversely affect good order and discipline. Convictions for consensual sodomy have been overturned in military courts under Lawrence in both United States v. Meno  and United States v. Bullock. 
On December 26, 2013, President Barack Obama signed into law the National Defense Authorization Act for Fiscal Year 2014, which repealed the ban on consensual sodomy found in Article 125. 
The table indicates which acts or groups were covered under each sodomy law, as pertaining to consenting adults. It also indicates the year and method of repeal or strikedown.
