Aegis America, a tax-exempt 501(c)(3) nonprofit, was formed in response to the interests of U.S. citizens committed to its mission. Aegis America supports the work of The Aegis Trust through fundraising, global engagement, outreach and education. Its founding committee is headquartered in Chicago, Illinois with local committees being organised in D.C., Los Angeles, New York and San Francisco.

While much of the work of Aegis has been operationally focused in Rwanda and the UK, the organisation has a global mission to work toward the eradication of genocide. Establishing a stronger presence in the United States through Aegis America is a key part of growing the body of support that will be needed to fulfil this mission.
