LGBTQ+ conservatism in the United States is a political and social ideology within the community that largely aligns with the American conservative movement, emphasizing fiscal and libertarian values over social conservatism. In the post-World War II era, early homophile organizations, like the Mattachine Society, faced immense pressure to disavow their ties to Marxist ideologies amidst pervasive anti-communist fears. This led to a significant turning point in 1953, when the Mattachine Society's convention rejected 'leftist' views and elected new leaders without Communist Party affiliations.

Activism strategies also diverged, with "assimilationist" approaches working within political systems (e.g., lobbying) and "liberationist" tactics challenging them (e.g., protests), though even the latter sometimes adopted conservative appearances. During this period, no major political party openly supported gay rights, and in 1953, Republican President Dwight Eisenhower signed Executive Order 10450, which effectively barred openly gay and lesbian individuals from federal government service. This history reflects a complex interplay of internal ideological divides and external societal and governmental pressures that shaped the early gay rights movement.
