Lesbian, gay, bisexual, and transgender (LGBT) social movements are social movements that advocate for the equalized acceptance of LGBT+ people in society.  In these movements, LGBT people and their allies have a long history of campaigning for what is now generally called "LGBT rights", sometimes also called "gay rights" or "gay and lesbian rights".  Although there is not a primary or an overarching central organization that represents all LGBT+ people and their interests, numerous LGBT rights organizations are active worldwide.  The earliest organizations to support LGBT+ rights were formed in the 19th century. LGBT rights in communism has evolved radically throughout history.

LGBT rights in the Maldives are still in development as the country continues to strongly oppose law reform and LGBT rights developments through the Universal Periodic Review and other recommendations.  The Maldives was one of the initial 57 (now 54) members to sign a document opposing LGBT rights in the UN declaration on sexual orientation and gender identity in 2008.  In 2011, the Maldives further rejected a landmark proposal for an LGBT rights resolution in the United Nations Human Rights Council put forth by the Republic of South Africa.  Since then, many other attempts to develop LGBT Rights in the country have been rejected by the Government.  Homosexuality was originally criminalised in the Maldives in the 1880s.  The Maldives law criminalises homosexuality and prescribes criminal penalties for same-sex sexual conduct and relationships.  The Penal Code of the Maldives works with Islamic Shariah Law to punish any acts relating to homosexuality through prison sentences, death penalties, and lashings.  Despite this, homosexuality is rarely prosecuted but remains a social taboo where sexual orientation discrimination occurs frequently and those in the LGBT community are subject to hate crimes and other human rights violations. Laws affecting lesbian, gay, bisexual, and transgender (LGBT) people vary greatly by country or territory—everything from legal recognition of same-sex marriage or other types of partnerships, to the death penalty as punishment for same-sex romantic/sexual activity or identity.
