The Asia-Pacific Center for Security Studies (APCSS) is a United States Department of Defense regional study, conference, and research center established in Honolulu, Hawaii, United States on September 4, 1995. The Center supports the United States Pacific Command (PACOM) theater security cooperation strategy of maintaining positive security relationships with nations in the Asia-Pacific region. With its non-warfighting, academic focus, the APCSS seeks to build on the strong bilateral relationships between the PACOM, and Asia-Pacific region governments and their armed forces, by focusing on the broader multilateral approach to addressing regional security issues and concerns.
