American Atheists advocates for science- and reason-based public policy and defends the absolute separation of religion and government. Since 1963, we have fought for equality under the law for all Americans, regardless of religion, and an end to the promotion of religious dogma in our nation’s laws.

We’re Standing For:




Our Vision

American Atheists envisions a world in which public policy is made using the best evidence we have rather than religious dogma and where religious beliefs are no longer seen as an excuse for bigotry or cause to receive special treatment from the government. We fight for religious equality for all Americans by protecting what Thomas Jefferson called the “wall of separation” between state and church created by the First Amendment.

We strive to create an environment where atheism and atheists are accepted as members of our nation’s communities and where casual bigotry against our community is seen as abhorrent and unacceptable. We promote understanding of atheists through education, outreach, and community building and work to end the stigma associated with being an atheist in America.

American Atheists relies on the generosity of our members and supporters to protect the separation of religion from government and advocate for reason-based public policy. We need your help today.

Thanks in part to the work of American Atheists, the number of atheists in the United States continues to grow and attitudes toward atheists are shifting. However, misconceptions about atheists still exist and members of our community still face discrimination at home, work, and school. Help us continue to elevate atheists and educate the public about atheism by making a tax-deductible gift today.
