The Dunn Foundation (formerly Dunn’s Foundation for the Advancement of Right Thinking) is a family foundation based in Delaware that makes grants to right-of-center organizations that advance libertarian principles of free enterprise, smaller government, deregulation, private property rights, and individual liberty.  It also supports organizations that fight government overreach and corruption. 
The name of the foundation was changed from Dunn’s Foundation for The Advancement of Right Thinking to The Dunn Foundation in 2016.  The Foundation was founded by investor William Dunn, a free-market advocate who sits on the boards of a number of libertarian organizations; his wife Rebecca, also a free-market activist, is a trustee of the Dunn Foundation. 
The Dunn Foundation (formerly known as Dunn’s Foundation for The Advancement of Right Thinking) was founded in the early 1990s in Florida by William A. Dunn to provide grants to organizations that promote classical liberal values of individual liberty, small government, and free enterprise. 
Grants are focused in the United States yet some grantees work globally to disseminate the organization’s principles abroad. Research on economic policy and the dissemination of the findings in furtherance of the organization’s principles, legal challenges to onerous government policies, fighting against government corruption, and the education of the nation’s youth are key areas supported by Dunn Foundation grants.
The Dunn Foundation supports a number of free-market policy and advocacy organizations such as Students for Liberty, Political Economy Research Center, Institute for Justice, Manhattan Institute for Policy Research, Pacific Legal Foundation, Foundation for Government Accountability, Foundation for Equal Rights in Education, Cato Institute, and Atlas Economic Research Foundation.
