Lesbian, gay, bisexual, and transgender (LGBT) social movements are movements that advocate for the full 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 no one organization that represents all LGBT people and their interests, numerous LGBT rights organizations are active worldwide.

A commonly stated goal among these movements is social equality for LGBT people. Some have also focused on building LGBT communities or worked towards liberation for the broader society from heterosexism and homophobia.

LGBT movements organized today are made up of a wide range of political activism and cultural activity, including lobbying, street marches, social groups, media, art, and research.
