The American Crystallographic Association, Inc. (ACA) is a non-profit, scientific organization for scientists who study the structure of matter via crystallographic methodologies. Since its founding in 1949 it has amassed over 2000 members worldwide.

A quarterly magazine, called ACA RefleXions, is published in addition to a scholarly journal. Structural Dynamics is a peer-reviewed, open access, online-only journal co-published by ACA and AIP Publishing. It highlights research articles on structural determination and dynamics of systems, enabled by the emerging new instruments (e.g. XFELs, high harmonic generation, ultra-short electron sources, etc.) and new experimental and theoretical methodologies.
