The Atlantic Council is an American think tank in the field of international affairs, favoring Atlanticism, founded in 1961. It manages sixteen regional centers and functional programs related to international security and global economic prosperity. It is headquartered in Washington, D.C. It is a member of the Atlantic Treaty Association.
Melvin Small of Wayne State University wrote that, especially in its early years, the Council's real strength lay in its connections to influential policymakers. The Council early on found a niche as "center for informal get-togethers" of leaders from both sides of the Atlantic, with members working to develop "networks of continuing communication".
