Since 1947, Americans United has led the way in defending the separation of church and state, the cornerstone of religious liberty in America. As a non-sectarian, non-partisan organization, AU's membership includes Christians, Jews, Buddhists, people with no religious affiliation and others. Democrats, Republicans and independents have joined our ranks.

Americans United is an independent organization with no ties to any larger group or political movement. We are a true grassroots organization. Thanks to your support, Americans United is able to defend separation of church and state in the courts, educate legislators, work with the media to inform Americans about religious freedom issues and organize local chapters all over the country.
