The Atlantic Council is a nonpartisan think tank based in the United States, established in 1961 by former U.S. Secretaries of State Dean Acheson and Christian Herter. Its mission is to foster cooperation and leadership between North America and Europe, addressing global challenges through transatlantic partnerships. The Council supports the Atlantic Alliance, particularly NATO, by enhancing public understanding and facilitating policy dialogue on international security, economic prosperity, and political cooperation.

The Atlantic Council produces a variety of research publications, including policy papers, reports, and academic journals. It hosts forums and conferences that connect policymakers, experts, and leaders from around the world. With sixteen regional centers and functional programs, the Council addresses issues such as climate change and global economic policy. It also engages in public education and advocacy through media outreach and develops future leaders to sustain transatlantic cooperation and global engagement.
