Americans United for Separation of Church and State is a national nonprofit advocacy organization dedicated to protecting religious freedom and defending the constitutional principle of church state separation in the United States. Founded in 1947, the organization works to ensure that government remains neutral on matters of religion and that individuals are free to practice any faith, or no faith, without discrimination or government interference.
The organization engages in litigation, public education, policy advocacy, and grassroots organizing to address issues involving religious liberty, public education, civil rights, reproductive freedom, LGBTQ+ equality, and government neutrality in matters of faith. Americans United frequently participates in court cases and legislative efforts involving First Amendment protections and the role of religion in public institutions.
Americans United provides educational resources, legal analysis, action campaigns, and organizing opportunities for individuals who want to support religious freedom and constitutional protections. The organization brings together people from diverse religious backgrounds as well as nonreligious communities to advocate for equal treatment under the law and the protection of individual rights.
For activists, educators, journalists, students, legal researchers, and community organizers, Americans United offers valuable resources for understanding church state separation, monitoring legislation, tracking court cases, and participating in advocacy efforts. Its work helps inform public discussions about democracy, civil liberties, public education, and constitutional rights.
