The Wisconsin Project on Nuclear Arms Control is a private, nonprofit, and nonpartisan organization based in Washington, D.C., in cooperation with the University of Wisconsin. Since 1986, the Project has been dedicated to researching and advocating for the prevention of the spread of nuclear and other weapons of mass destruction. Committed to stopping arms proliferation at its source, the Project works to expose dangerous export transactions and collaborates with countries to enhance their export control systems.

Their impactful work has led to significant developments, such as forcing Israel to return nuclear material imported for improper purposes, strengthening export control systems in Germany, and triggering tighter restrictions by the U.S. Congress on the sale of sensitive technologies. The Project also provides direct support to governments globally, training thousands of export control officials to strengthen regulations.

The Wisconsin Project's main programs include the Risk Report database and the Iran Watch website, which are vital resources for governments and companies worldwide in managing risks and monitoring companies suspected of links to weapons programs. Supported by the U.S. government and private foundations, the Wisconsin Project continues to be a crucial player in global nonproliferation efforts.
