Law for the Purpose of Protecting Children from Information Advocating a Denial of Traditional Family Values, commonly known as the Russian anti-LGBT law or as the Russian anti-gay law, is a law of Russia. It was unanimously passed by the State Duma on 11 June 2013 (with only one member abstaining—Ilya Ponomarev), unanimously passed by the Federation Council on 27 June 2013, and signed into law by President Vladimir Putin on 30 June 2013.

The stated purpose of the Russian government for the law is to prevent the presentation of the LGBT community as a normal part of Russian society under the argument that LGBT rights in Russia contradict traditional Russian values. The statute amended the Russian law On Protecting Children from Information Harmful to Their Health and Development and the Code of the Russian Federation on Administrative Offenses, to prohibit the distribution of "propaganda of non-traditional sexual relationships" among minors. This definition includes materials that "raise interest in" such relationships, cause minors to "form non-traditional sexual predispositions", or "[present] distorted ideas about the equal social value of traditional and non-traditional sexual relationships." Businesses and organizations can also be forced to temporarily cease operations if convicted under the law, and foreign nationals may be arrested and detained for up to 15 days then deported, or fined up to 5,000 rubles and deported.

The support of the Russian government for the law appealed to social conservatives, religious conservatives, and Russian nationalists. The law was condemned by the Venice Commission of the Council of Europe (of which Russia was a member of at the time of the enactment of the law), by the United Nations Committee on the Rights of the Child and by human rights organizations, such as Amnesty International and Human Rights Watch. The statute was criticized for its broad and ambiguous wording (including the aforementioned "raises interest in" and "among minors"), which many critics characterized as being an effective ban on publicly promoting LGBT culture and LGBT rights. The law was also criticized for leading to an increase and justification of homophobic violence, while the implications of the laws in relation to the then-upcoming Winter Olympics being hosted by Sochi were also cause for concern, as the Olympic Charter contains language explicitly barring various forms of discrimination.

In December 2022, an amendment to the law was signed into law by Putin, prohibiting the distribution of "propaganda of non-traditional relationships" among any age group. It also prohibits the distribution of materials that promote transgender identity among minors.

Despite the fact that the cities of Moscow and Saint Petersburg have been well known for their thriving LGBT communities, there has been growing opposition towards gay rights among politicians since 2006. The city of Moscow has actively refused to authorize gay pride parades, and former Moscow mayor Yuri Luzhkov supported the city's refusal to authorize the first two Moscow Pride events, describing them as "satanic" and blaming western groups for spreading "this kind of enlightenment" in the country. Social democratic Fair Russia member of parliament Alexander Chuev was also opposed to gay rights and attempted to introduce a similar "propaganda" law in 2007. In response, prominent LGBT rights activist and Moscow Pride founder Nikolay Alexeyev disclosed on the television talk show К барьеру! (K bar'yeru!) that Chuev had been publicly involved in same-sex relationships prior to his time in office.

In 2010, Russia was fined by the European Court of Human Rights under allegations by Alexeyev that cities were discriminating against gays by refusing to approve pride parades. Although claiming a risk of violence, the court interpreted the decisions as being in support of groups which oppose such demonstrations. In March 2012, a Russian judge blocked the establishment of a Pride House in Sochi for the 2014 Winter Olympics, ruling that it would "undermine the security of Russian society", and that it contradicted with public morality and policies "in the area of family motherhood and childhood protection." In August 2012, Moscow upheld a ruling blocking Nikolay Alexeyev's requests for 100 years' worth of permission to hold Moscow Pride annually, citing the possibility of public disorder.

The bill "On Protecting Children from Information Harmful to Their Health and Development" introduced laws which prohibited the distribution of "harmful" material among minors. This includes content which "may elicit fear, horror, or panic in children" among minors, pornography, along with materials which glorify violence, unlawful activities, substance abuse, or self-harm. An amendment to the law passed in 2012 instituted a mandatory content rating system for material distributed through an "information and telecommunication network" (covering television and the internet), and established a blacklist for censoring websites which contain child pornography or content glorifying drug abuse and suicide.

The 2013 amendment, which added "propaganda of non-traditional sexual relationships" as a class of harmful content under the law was, according to the Government of Russia, intended to protect children from being exposed to content that portrays homosexuality as being a "behavioural norm". Emphasis was placed upon a goal to protect "traditional" family values; bill author Yelena Mizulina (the chair of the Duma's Committee on Family, Women, and Children, who has been described by some as a "moral crusader"), argued that "traditional" relations between a man and a woman required special protection under Russian law. The amendment also expanded upon similar laws enacted by several Russian regions, including Ryazan, Arkhangelsk (who repealed its law shortly after the passing of the federal version), and Saint Petersburg.
