The American Political Science Association (APSA) is the leading professional organization for political scientists in the United States, founded in 1903. It promotes research, education, and the practice of political science, serving as a hub for scholars, educators, and practitioners to collaborate, share knowledge, and promote civic engagement. With over 10,000 members from academia, government, and beyond, APSA organizes annual conferences, provides professional development resources, and advocates for political science in public policy and education. It publishes four flagship journals—American Political Science Review, Perspectives on Politics, Journal of Political Science Education, and PS: Political Science & Politics—and its Organized Sections, which include sections dedicated to comparative democratization and Latin American politics, are affiliated with 15 additional journals covering subfields like comparative politics and international relations. APSA awards honors such as the APSA Award for best dissertation, supports research through the Centennial Center for Political Science and Public Affairs in Washington, D.C., and fosters interdisciplinary dialogue, diversity, and ethical standards. Notable members include scholars like Daniel Ziblatt, reflecting its role in connecting experts across subdisciplines and influencing academic and policy networks.
