The ACLU is our nation's guardian of liberty, working daily in courts, legislatures and communities to defend and preserve the individual rights and liberties that the Constitution and laws of the United States guarantee everyone.

To defend the Constitution and keep America safe and free, the ACLU of Arizona needs the support of every Arizonan who cares about protecting our precious civil liberties.

You can help defend the traditional American values enshrined in the Bill of Rights by supporting the work of the American Civil Liberties Union, and its local affiliate, the American Civil Liberties Union of Arizona.

The ACLU of Arizona was formed and officially chartered by the national organization over 50 years ago. In September of 1958, three Tucson ACLU members sent a questionnaire to the 120 other members of the national ACLU in Arizona asking them if they thought there was a need for a chapter in Arizona. The response was a resounding "yes". Since that time, we have fought to defend individual rights in Arizona through litigation, legislation, and public education.
