The Conservative Political Action Conference (CPAC; /ˈsiːpæk/SEE-pak) is an annual political conference attended by conservative activists and elected officials from across the United States. CPAC is hosted by the American Conservative Union (ACU). More than 100 other organizations contribute in various ways.
In 2011, ACU took CPAC on the road with its first Regional CPAC in Orlando, Florida. Since then ACU has hosted regional CPACs in Chicago, Denver, St. Louis, and San Diego.
