The American Psychological Association of Graduate Students (APAGS) is a constituency group within the American Psychological Association (APA) that represents APA graduate student affiliate members.

Founded in 1988, APAGS represents approximately one-third of all members of the American Psychological Association, making it one of the largest constituency groups within the association and the largest group of organized graduate psychology students worldwide.

[1] APAGS was formed by David Pilon and Scott Mesh, who were graduate students in clinical psychology.

[2] Psychologists Raymond D. Fowler, Pierre Ritchie, Ellin Bloch,[2] Virginia Staudt Sexton, John D. Hogan, Jeff Nevid, and Louis Primavera helped Pilon and Mesh lay the groundwork to form APAGS at the August 1988 meeting of the American Psychological Association in Atlanta, Georgia.

APAGS has gained voting seats in APA governance groups such as the Committee on Accreditation and the Council of Representatives.
