The mission of the Secular Coalition for America is to increase the visibility of and respect for nontheistic viewpoints in the United States, and to protect and strengthen the secular character of our government as the best guarantee of freedom for all. The Secular Coalition for America is a 501(c)(4) advocacy organization whose purpose is to amplify the diverse and growing voice of the nontheistic community in the United States. We are located in Washington, D.C. for ready access to government, activist partners and the media. Our staff lobbies U.S. Congress on issues of special concern to our constituency. Our member organizations are established 501(c)(3) nonprofits who serve atheists, agnostics, humanists, freethinkers and other nontheistic Americans. Their purpose in founding the coalition was to formalize a cooperative structure for visible, unified activism to improve the civic situation of citizens with a naturalistic worldview. A number of additional organizations have endorsed our mission statement.
