The American Association for Public Opinion Research (AAPOR) is a professional organization of more than 2,000 public opinion and survey research professionals in the United States and from around the world, with members from academia, media, government, the non-profit sector and private industry. AAPOR publishes three academic journals: Public Opinion Quarterly, Survey Practice and the Journal of Survey Statistics and Methodology. It holds an annual research conference and maintains a "Code of Professional Ethics and Practices", for survey research which all members agree to follow. The association's founders include pioneering pollsters Archibald Crossley, George Gallup, and Elmo Roper.

AAPOR's stated principle is that public opinion research is essential to a healthy democracy, providing information crucial to informed policy-making and giving voice to people's beliefs, attitudes and desires. Through its annual conference, standards and ethics codes and publications, AAPOR seeks to promote a better public understanding of the role of public opinion research in a democracy, as well as the sound and ethical conduct and use of public opinion research.
